Factory Acceptance Test of Multi-Station Thermoformers | AIRAYS Quality Inspection Standard

Introduction
Equipment stability and consistent mass production performance are the core guarantees for downstream food packaging manufacturers to achieve efficient production. As a professional manufacturer of high-end plastic thermoforming equipment, AIRAYS (Wenzhou Rayshape Machinery Co., Ltd.), a subsidiary of ELEMOTION, implements a standardized and rigorous Factory Acceptance Test (FAT) for every multi-station positive-negative pressure thermoformer before delivery.
All testing procedures are completed independently in our factory workshop. The complete machine undergoes full-cycle simulated mass production operation to verify the coordination accuracy, operational stability, finished product molding quality and system reliability of each functional module, ensuring that every delivered device fully meets customer production standards and industry quality specifications.
Full Process Verification of Standard FAT Testing
The factory acceptance test covers the entire working workflow of the multi-station thermoformer, including sheet unwinding, servo feeding, constant temperature heating, positive-negative pressure molding, punching, in-mold cutting, automatic stacking and edge scrap recycling. The whole machine operates continuously with real plastic sheets to simulate actual factory production conditions, avoiding unloaded single-function simple testing.
1. Material Feeding and Conveying System Test
The double-station large-diameter unwinding structure and full-servo feeding system are fully started during the test. The equipment automatically completes sheet unwinding and constant-speed conveying. The system accurately verifies the sheet conveying length, running speed and operating stability, effectively avoiding sheet slipping, deviation and falling problems in actual production, and laying a foundation for consistent molding of subsequent products.
2. Zoned Constant Temperature Heating System Test
Equipped with an upper and lower four-section independent heating system, the machine adopts ±1℃ precise zoned temperature control technology. During the acceptance test, the heating temperature of each zone is adjusted according to PP, PET, PLA and recycled material characteristics to detect temperature uniformity and heating response speed. This core test ensures that the sheet can be heated evenly and stably, solving common molding defects such as uneven thickness and warping caused by temperature deviation.
3. Positive-Negative Pressure Molding Accuracy Test
The core molding station performs high-frequency continuous cycle operation. Through the coordinated action of compressed air positive pressure and vacuum negative pressure, the equipment completes the molding of food-grade packaging products such as fresh food trays, egg trays and fresh-keeping sealing boxes. The inspectors check the product cavity completeness, corner definition and wall thickness consistency one by one to verify the rationality of the molding pressure and mold matching accuracy.
4. Punching and In-Mold Cutting Function Test
For 4-station customized models, the independent punching station is fully tested to verify the precision of vent hole forming of fruit and vegetable trays and egg trays. All models complete in-mold cutting linkage tests to ensure clean separation between finished products and edge materials, effectively reducing burrs and flash defects and improving the yield rate of finished products.
5. Automatic Stacking and Scrap Recycling Test
The automatic stacking station runs continuously to realize orderly layered collection and arrangement of finished packaging products, which greatly reduces manual contact, avoids product pollution and damage, and improves production automation. At the same time, the servo-driven edge scrap rewinding system operates synchronously to recycle production waste, realizing clean and environmentally friendly standardized production.
6. Whole Machine Linkage and Finished Product Inspection
During the long-term continuous operation test, the coordination of each station of the whole machine is monitored in real time. After the test, professional inspectors sample and detect the size accuracy, surface flatness and molding stability of the finished products. Only equipment that fully passes all performance indicators and quality standards can be arranged for delivery.
Core Value of AIRAYS Standardized FAT Testing
Different from simple factory debugging in the industry, AIRAYS takes customer actual production scenarios as the core. The full-load simulated production test can effectively eliminate potential hidden dangers such as unstable temperature control, inaccurate feeding and poor station linkage. It ensures that the equipment can adapt to the stable mass production of various materials including conventional plastic materials and biodegradable & recycled materials after arriving at the customer's factory.
Adhering to strict factory acceptance standards is a key link for AIRAYS to control equipment quality. In the future, we will continue to optimize testing procedures and technical standards, provide high-stability and high-automation thermoforming equipment for global packaging manufacturers, and create reliable production value for customers.
Product Application & Support
AIRAYS multi-station positive-negative pressure thermoformers support mass production of fresh food trays, egg trays, takeaway food containers, fresh-keeping boxes and plastic cup lids, and are compatible with PP, PET, PS, PLA biodegradable materials and r-PET/r-PP recycled materials. We provide standard models and customized non-standard equipment solutions according to customer mold sizes and production demands.
