It is currently operating stably in overseas markets such as Uzbekistan and Saudi Arabia, as well as in large-scale projects in Jiangxi, Guizhou, and Fujian provinces in China, adapting to the raw material characteristics and production standards of different regions.
Q2: How is the equipment's production efficiency and stability? Is it capable of continuous operation?
A: The FK008-Ⅲ achieves a stable production speed of 110-120pcs/min. Equipped with a full servo control system and internationally renowned brand components (Schneider PLC, NSK bearings, etc.), the dynamic error is less than 0.01mm, ensuring smooth sealing and precise dimensions even at high speeds. The equipment supports operation in a wide temperature range of -20℃ to 60℃. Its dust-resistant and voltage fluctuation-resistant design results in a failure rate of less than 0.5%, enabling 30 days of continuous, downtime-free production, making it particularly suitable for large-scale mass production.
Q3: Compared to ordinary bag-making machines, what are its advantages in cost control?
A: The core advantages are concentrated in two aspects: raw material savings and energy consumption optimization:
1. Patented bottom sealing technology: Utilizing single-sided film material and a narrow bottom overlap design, it saves $1 in raw material costs for every 500 bags produced. A production line with an annual capacity of 30 million bags can save $60,000 annually.
2. Intelligent energy-saving system: Vector frequency conversion technology reduces motor energy consumption by 10%-30%, automatically entering sleep mode during standby and intelligently boosting voltage under high load, saving tens of thousands of yuan in electricity costs annually.
3. AI visual inspection replaces manual labor: One operator can manage 3-4 machines simultaneously, reducing labor costs by 240,000-360,000 yuan per production line annually.
II. Technological Innovation and Patents: These Cutting-Edge Technologies Solve Industry Pain Points
Q4: What is the patented triangular bag opening technology? How is it superior to traditional designs?
A: This is Gachn's core innovation. It achieves bag opening formation through vacuum negative pressure, eliminating the need for easily damaged parts such as suction cups. Traditional bag-making machines' suction cups frequently contact materials, leading to wear, leakage, unstable bag opening formation, and high maintenance costs. The FK008-Ⅲ's contactless design not only offers faster forming speed and stronger stability but also reduces the replacement of easily damaged parts by 90%, lowering subsequent maintenance workload and costs.
Q5: What defects can the AI vision inspection system identify? What is its accuracy rate?
A: The system fully covers two major categories of problems: base fabric defects and bag-making defects. These include round threads, holes, coarse threads, joints, and scratches in the base fabric, as well as bottom sticker misalignment, sticker folding, missing corners, and incomplete sealing during the bag-making process. AI adaptively identifies defects without manual marking, achieving a false negative rate as low as 0.05%. Compared to manual inspection, the accuracy is improved by more than 3 times, and defect data can be tracked in real time, providing a basis for production process optimization.
Q6: Is the equipment highly automated? Does it require high skill levels from operators?
A: The equipment uses a user-friendly human-machine interface with a fully Chinese/English control panel. Parameter settings, fault warnings, production counting, and other functions are clearly displayed. Ordinary workers can operate it independently after 1-2 days of training, and the maintenance team only needs 2 mechanical engineers and 1 electrical engineer per shift. We also provide detailed Chinese and English operation manuals and video tutorials, and on-site training combines hands-on practice to ensure immediate usability upon production.
III. Installation, Commissioning, and After-Sales Service: Is the overseas project implementation guaranteed?
Q7: What are the installation and commissioning procedures after overseas customers purchase the equipment?
A: Gachn provides turnkey service with complete transparency throughout the process:
1. 100% full-machine testing is completed before equipment leaves the factory to ensure compliance with export standards;
2. Standard ocean-going packaging is used for sea freight, with a professional customs clearance team assisting with procedures;
3. Upon arrival at the site, 8 professional technicians provide on-site service, completing installation, commissioning, and trial production within 30 days;
4. During the trial production phase, parameters will be optimized based on actual output until the product qualification rate reaches the agreed standard before acceptance.
Q8: What does the training include? How is after-sales technical support guaranteed?
A: Training adopts a combined "theory + practice" model, covering equipment structure principles, daily operation, parameter adjustment, common troubleshooting, maintenance, etc., and customized training materials are also provided. Regarding after-sales support, the equipment enjoys a 12-month full-machine warranty (including electrical and mechanical systems), and free upgrades to the electrical control system within 3 years; whether domestic or overseas, the after-sales team will respond to fault inquiries within 24 hours, and in emergencies, technicians can be coordinated for on-site service.
Q9: What are the requirements for the factory and supporting facilities for the equipment?
A: The space required for a single unit is 12m long × 7.5m wide × 2.5m high. It is recommended that the entire production line factory be no less than 85m × 60m (including equipment placement and material handling area). Supporting facilities must meet the following requirements: 380V three-phase five-wire power supply (total power 150KW, operating power 60KW), 0.6m³/h cooling water flow, and 6-7 bar compressed air (3m³/min). These are standard configurations for conventional industrial production; customers can prepare them in advance according to their own circumstances.
IV. Practical Application and Expansion: These Details Help You Avoid Production Risks
Q10: Does the equipment have special requirements for raw materials? Is it compatible with PP raw materials from different regions?
A: Raw materials must meet the following standards: PP drawing grade raw materials (MFI 3.5-5.0g/10min, 230℃), coating grade raw materials (PP coating grade MFI 18-40g/10min, or 85% PP + 15% LDPE mixed raw materials). Additives can include conventional auxiliaries such as calcium carbonate masterbatch. Our equipment is adapted to the characteristics of raw materials in different regions worldwide.
