What is a dry-installed pump? As the name suggests, a dry-installed pump means that the pump itself will not be directly immersed in the liquid, but will be installed on the outside of the pipe. In this way, the motor and key components of the pump are kept in a dry environment, avoiding direct contact between the liquid and these components. In other words, this pump is like a "dry worker" who is "away from the water source", which can be said to be a "smart" pump.

 

Benefits of dry-installed pumps

Reduce the number of maintenance times Because dry-installed pumps are away from liquids, motors and other important components can avoid contact with corrosive liquids. After long-term use, the pump will also have less loss, reducing the need for frequent maintenance and extending its service life. Think about it, fewer repairs, not only save money, but also save time!

 

Safer

For many working environments, the safety of the pump is crucial. The design of the dry-mounted pump ensures the safety of key parts such as the motor, prevents direct contact between water and electricity, reduces the risk of electrical failure, and is safer to use.

 

Easy to install

Traditional pumps need to be installed in a pool, underground or inside a pipe, which means that the installation process can be very complicated and time-consuming. Dry-mounted pumps do not require such tedious steps and can be easily installed directly on the outside of the pipe, greatly reducing the difficulty and time of installation.

 

 Energy-saving and efficient

Dry-mounted pumps usually use high-efficiency motors and designs to provide efficient water flow at lower energy consumption. Not only can you save energy costs, but you can also achieve ideal work efficiency.

In the production of plastic woven valve bags, the printing process directly affects the appearance, texture and market competitiveness of the product. As the core equipment for printing plastic woven fabrics and composite films, the "satellite" and "stacked" layouts of web-fed gravure printing machines have different focuses in the field of plastic woven valve bags. Gachn will focus on the characteristics of these two models in the printing of plastic woven valve bags to help you find a more suitable production tool.

Plastic woven valve bags are widely used in chemical, building materials, food and other industries because of their moisture resistance, load-bearing and sealing properties. The printing substrate is mostly plastic woven fabric (PP/PE woven fabric). The surface of this type of material is relatively rough, the thickness is relatively uniform, but there is a certain degree of ductility, which puts forward special requirements for the adaptability of printing equipment. According to the arrangement of the printing unit, the mainstream gravure printing machine is divided into satellite type and stacked type, and both have their own advantages in the production of plastic woven valve bags.

1. Satellite web-type gravure printing machine: the "stabilizer" for high-precision printing of plastic woven valve bags

The satellite structure, with its "all stars around the moon" layout, is ideal for printing plastic woven valve bags that require high overprint accuracy.

Core structure

All gravure plate cylinders are arranged around a central impression cylinder, like satellites around a planet. For plastic woven valve bag printing, 4-6 printing units are usually configured to meet the multi-color pattern requirements of most products.

 

Workflow

After the plastic woven base material (woven fabric or composite woven film) is unwound from the feeding section, it enters the printing area through the tension control roller, closely adheres to the surface of the central impression cylinder, and passes through each printing unit in turn to complete multi-color overprinting. For valve bags that need double-sided printing (such as brand patterns on the front and product instructions on the back), the reverse printing device can be used to achieve efficient production of "single-sided single color + other side multi-color", and finally rewound into rolls by the receiving section.

 

The core advantages of plastic woven valve bags

（1）High overprinting accuracy and fit to rough surface: There are warp and weft lines on the surface of plastic woven fabric. The satellite-type central embossing roller is rigid, which can make the substrate evenly stressed and reduce the overprinting deviation caused by the unevenness of the woven layout. It is especially suitable for printing valve bags with fine text, QR codes or complex patterns (such as warning signs of chemical products and brand logos of grain packaging).

（2）Reduce substrate stretching deformation: Although the ductility of plastic woven fabric is lower than that of film, it may still be slightly stretched due to uneven tension during high-speed printing. The satellite-type single roller transmission throughout the whole process greatly reduces the risk of stretching and avoids "elongation" or "misalignment" of the pattern.

（3）Stability is suitable for mass production: Plastic woven valve bags are mostly batch orders. The satellite-type single embossing point reduces tension fluctuations, which can ensure the consistency of long-term continuous printing and reduce the scrap rate.

 

Limitations in the field of plastic weaving

（1）Drying efficiency is challenging for thick substrates: woven fabrics and composite films absorb a large amount of ink, while the satellite unit spacing is short, and the drying space for solvent-based inks is limited. A powerful drying system (such as high-temperature hot air circulation) is required, otherwise "smudge" problems may occur.

（2）Maintenance adaptability is slightly weaker: In woven printing, the printing plate is easily attached to the fluff of the woven fabric and needs to be cleaned frequently. However, the compact structure of the satellite results in a small operating space, and the cleaning and plate changing efficiency is slightly low.

 

Applicable to plastic woven valve bag scenarios

（1）Industrial-grade valve bags (such as cement bags and chemical raw material bags) made of thick woven fabrics or coarse textured substrates;

（2）Customized orders requiring complex patterns with more than 8 colors or special processes (BOPP lamination);

（3）Manufacturers that print valve bags with a width of ≥1 meter, or that produce multiple substrates such as paper and non-woven fabrics.

 

2. Stacked web-feed gravure printing machine: a versatile tool for flexible production of plastic woven valve bags

The stacking type is designed with independent units like "stacked" and is more flexible in the diversified production of plastic woven valve bags.

 

Core structure

The printing units are stacked vertically on the main wallboard, and each unit is equipped with an independent impression cylinder, which is uniformly driven by a gear system. For the plastic woven industry, 2-8 color groups can be flexibly configured, and even auxiliary units such as cold stamping and lamination can be added.

 

Workflow

After unwinding, the plastic woven substrate passes through the stacked printing units in sequence according to the preset path, and each unit completes one-color printing. Due to the large spacing between units, there is enough space for the substrate to pass through the drying device after printing before entering the next color group. The receiving department can choose ordinary rewinding or reserve tension for subsequent bag making processes according to needs.

 

Core advantages of plastic woven valve bags

（1）Fully dried, suitable for thick substrates: plastic woven cloth absorbs a large amount of ink, the stacked unit spacing is wide, and a multi-stage drying system (such as infrared preheating + hot air drying) can be installed to ensure that the ink is thoroughly dried, especially suitable for industrial valve bags printed with solvent-based inks.

（2）Easy operation and maintenance: The independent unit design makes plate changing and cleaning more convenient. When dealing with the common "fluff pollution" problem in plastic woven printing, the machine can be quickly stopped for cleaning to reduce production interruption time.

（3）Flexible expansion to meet customized needs: plastic woven valve bags often need to add color groups (such as 8-color complex patterns) or add special processes (such as local UV varnish to improve wear resistance) according to customer requirements. The stacked type can be easily expanded and configured to adapt to small batches and multiple batches of customized orders.

（4）Adapt to wide-format substrates: For printing of large-size valve bags (such as width ≥1 meter) in the chemical and building materials industries, the stacked type has more advantages in wide-format stability.

 

Limitations in the field of plastic weaving

(1) High requirements for tension control for overprinting accuracy: Plastic woven fabrics are transferred between multiple independent impression cylinders over a long path. Improper tension control may cause overprinting deviations, and a high-precision tension control system (such as magnetic powder brake + tension sensor) is required.

(2) Increase in equipment height workshop requirements: The vertical stacking structure results in a high equipment height, and it is necessary to ensure that the workshop has sufficient floor height (usually ≥4 meters).

 

Applicable to plastic woven valve bag scenarios

（1）Industrial-grade valve bags (such as cement bags and chemical raw material bags) made of thick woven fabrics or coarse textured substrates;

（2）Customized orders requiring complex patterns with more than 8 colors or special processes (BOPP lamination);

（3）Manufacturers that print valve bags with a width of ≥ 1 meter, or that produce multiple substrates such as paper and non-woven fabrics.

 

3. Satellite type vs. stacked type: comparison of core indicators of plastic woven valve bag printing

 

Comparison Dimension	Satellite	Stacked
Core Advantages	High overprint accuracy, suitable for fine patterns; strong batch stability	Complete drying, suitable for thick substrates; flexible operation and easy expansion
Typical color group	4-6 colors (meet most common patterns)	2-8 colors (expandable to more than 10 colors)
Equipment maintenance	Small space for changing plates/cleaning, a bit cumbersome when frequent	Independent unit, easy to operate and low maintenance cost

 

Conclusion: The key to selecting plastic woven valve bag printing

Satellite and stacked gravure printing machines are not "either this or that" in the production of plastic woven valve bags, but "precisely matched" according to product requirements. If your order focuses on fine patterns, thin composite substrates, and batch stability (such as food-grade valve bags), the satellite type is the first choice to ensure quality; if it focuses on thick substrates, multi-color customization, and wide-format production (such as industrial ton bag valve mouth printing), the stacked type can better improve production flexibility. In the plastic woven valve bag industry, the core of equipment selection is "adapting product characteristics and order models" - only by understanding the essential differences between satellite and stacked types can the printing process become a plus point to enhance product competitiveness.

In the plastic weaving packaging industry, laminating technology is a key link in improving product performance. Whether it is a common waterproof ton bag or a delicate BOPP film composite packaging, the precise operation of the laminating machine is indispensable. Today, we will deeply analyze the working principles of laminating machines and BOPP film laminating machines in the plastic weaving industry, and at the same time see how the Gachn Group-90-FMS800 dual-host plastic laminating machine, this "industry expert", stands out with its hard-core technology.

 

1. Raw material preparation and melt plasticization: the transformation from granules to melts

 

（1） Raw material input

Conventional plastic weaving laminating is mainly PE granules, and functional masterbatches such as antioxidants and masterbatches can be added according to needs, and enter the extruder through the hopper. When laminating BOPP film, in addition to base materials such as PE, raw materials with better compatibility with BOPP film are often selected to ensure a more stable composite effect. The GC90-FMS800 laminating unit is equipped with an automatic feeder, making the input of raw materials more convenient and efficient.

（2） Heating and melting

The heating device outside the extruder barrel (such as a resistance heating ring) cooperates with the internal rotating screw to "double-treat" the raw materials: heating the raw materials to a molten state (PE melting point 105-135℃, PP 160-170℃), and the screw shearing makes the melt mixed more evenly. The Gachn Group-90-FMS800 dual-host plastic laminating machine uses a Toudao refined screw with a diameter of 90mm. It is also equipped with a fast column screen changing machine, which can stabilize the extrusion volume. The maximum extrusion volume of a single machine can reach 200kg/h. The barrel screw material is 38CrMoAlA, which is sturdy and durable, ensuring the stable melting and plasticization of the raw materials. For BOPP film laminating, due to the high melting point of BOPP (165-175℃), the ceramic heaters (30kw each) and Omron automatic temperature control instruments (eight) of the unit can accurately control the temperature, ensuring that the raw materials are fully melted and avoiding high temperature damage to the BOPP film.

 

2. Melt extrusion film forming: the birth of uniform film

 

(1)Melt filtration and voltage stabilization

The melted melt is first filtered through the filter to remove impurities, and then enters the voltage stabilizing device. This step is particularly critical for BOPP film laminating - the surface of the BOPP film is flat. If the melt pressure is unstable, it is very easy to cause defects such as bubbles and uneven thickness after compounding. The relevant devices of the Gachn Group-90-FMS800 dual-host plastic laminating machine can effectively ensure the stability of the melt pressure and lay a good foundation for subsequent film forming.

 

(2)T-die extrusion

The melt is finally extruded through the "T-die". The die flow channel is designed in a gradual change, which can evenly distribute the melt to the entire width to form a molten film that matches the width of the substrate. BOPP film laminating requires higher die precision to ensure that the film can perfectly cover the surface of the BOPP film. Gachn Group-90-FMS800 dual-host plastic laminating machine adopts a T-type die with a width of 1050mm. The die block is adjustable from 200 to 1050mm, which is achieved by adjusting the plug-in plate with a hand wheel. The die material is 5 chromium nickel molybdenum, equipped with ten Omron automatic temperature control instruments and ten Taiwan-made thermocouples to ensure stable discharge, allowing the plastic melt to flow evenly in the die, avoiding dead corners and speed fluctuations.

 

3. Substrate pretreatment: Make the bond stronger

In order to enhance the adhesion between the laminating layer and the substrate, the pretreatment link is essential, and BOPP film is particularly dependent on this:

·Corona treatment: Oxidize the surface molecules of the BOPP film through high-voltage discharge, increase the surface tension, solve its "non-stick" problem, and effectively prevent delamination.

·Preheating: The preheating temperature of BOPP film needs to be strictly controlled at 40-60℃, which can not only reduce the temperature difference with the melt, but also avoid deformation caused by high temperature; the preheating temperature of conventional woven fabrics is slightly higher (50-80℃). The laminating machine of the GC90-FMS800 unit is equipped with a preheating roller with a diameter of 350MM, which can accurately control the preheating temperature and improve the bonding effect between the substrate and the melt.

 

4. Composite lamination: "Intimate bonding" of substrate and film

(1)Synchronous lamination

The pretreated substrate (woven fabric or BOPP film) is transported to the bottom of the die head by the guide roller and accurately aligned with the extruded molten film. BOPP film is thin and has good stiffness. It has extremely high requirements for the synchronization of the travel speed and the melt extrusion speed. It needs to be guaranteed by a precise control system to avoid wrinkles or uneven stretching. The control system of the Gachn Group-90-FMS800 dual-host plastic laminating machine adopts PLC and touch screen, which can complete the synchronous operation of the whole machine. Its laminating line speed can reach 250m/min, and the unwinding is equipped with EPC automatic deviation correction, with a stroke of ±100mm, ensuring the precise lamination of the substrate and the film.

(2)Roller lamination

The substrate and the melt enter the roller group (steel roller + rubber roller) and fit tightly under pressure: the laminating pressure of BOPP film is about 0.2-0.6MPa, and that of conventional woven fabric is about 0.3-0.8MPa. The steel roller passes cold water to quickly cool the melt and solidify it into shape; the rubber roller plays a buffering role to ensure uniform lamination. The hardness of the rubber roller for BOPP film needs to be more carefully selected. The Gachn Group-90-FMS800 dual-host plastic laminating machine has two sets of laminating machines, including a 700MM diameter matte large cold roller (manufactured by a professional roller factory, spiral cooling) and a 250mm diameter silicone roller, as well as two QGB 125×80 pressing cylinders, which can provide stable pressure to make the lamination tighter.

 

5. Cooling, shaping and winding: the final "shaping" of the finished product

(1)Cooling and curing

The composite product is further cooled by multiple sets of cooling rollers (circulating cooling water) to completely cure the laminating layer. The thermal stability of BOPP film is poor, and rapid cooling can reduce the heating time and ensure dimensional stability. The laminating thickness is usually 0.01-0.1mm, which can be adjusted by the die opening, extrusion speed, etc. The BOPP film laminating has stricter control over thickness uniformity. The total water supply of the GACHN GROUP-90-FMS800 dual-host plastic laminating machine is 0.5m³/min, which can provide sufficient water for the cooling system. The laminating thickness can be adjusted between 0.008-0.03mm to meet different needs.

(2) Traction and winding

The cooled finished product is transported to the winder by the traction roller (the speed is slightly higher than the pressure roller, forming a slight tension to ensure flatness). When winding the BOPP film, the tension must be precisely controlled to avoid stretching and deformation, and finally rolled into a neat coil to complete the entire laminating process. The winder of the GACHN GROUP-90-FMS800 dual-host plastic laminating machine is a double-station large roller friction winding frame, which can realize automatic roll change without stopping the machine. The maximum diameter of the winding is 1500mm, and the winding shaft is 8 inches. It is also equipped with an automatic tension roller device and a 5.5kw variable frequency dedicated motor and Huichuan inverter, which can accurately control the winding tension to ensure that the coils are neat and tight after winding.

Six. Unique advantages of GACHN GROUP-90-FMS800 dual-host plastic laminating machine machine.

In addition to the above-mentioned outstanding performance in each link, the unit has many highlights: the use of wall panels and aluminum alloy guide rollers is durable and ensures smooth operation; equipped with automatic trimming devices, including two sets of Aibo trimming related equipment, edge material blowing fan and edge material automatic recovery system, which can improve the utilization rate of raw materials; total power reaches 100kw, air flow rate 0.6m³/min, power and air source are sufficient; the overall dimensions are (14.5 length × 7.5 width × 3.5 height) m, and the structural layout is reasonable.

 

I hope that through this analysis, you will have a clearer understanding of the working principle of the laminating machine and the advantages of the GACHN GROUP-90-FMS800 dual-host plastic laminating machine.
