Precision Servo-Pneumatic Integration for Deep-Draw PP Trays
2026-02-20
Deep-draw polypropylene (PP) containers, often used for microwaveable meals and soup bowls, present a significant challenge in maintaining wall thickness uniformity due to the material's high shrinkage rate and thermal elasticity. Wenzhou Rayshape Machinery Co., Ltd., a core member of the Elemotion Group, has solved this through a sophisticated "Servo-Pneumatic Integration" system in its Plastic Thermoforming Machine. While the vacuum provides the final shaping force, the initial material distribution is governed by a servo-driven plug assist. This plug assist is not a simple linear actuator; it follows a multi-stage velocity curve programmed into the machine's PLC. By slowing down the plug just before it reaches the bottom of the mold, the machine prevents "bottom thinning" and ensures that the corners of the tray are reinforced. This mechanical precision is supported by the machine's four-column structural design, which provides the rigidity necessary to handle the high clamping pressures required for PP. The five-point structural connecting rod system ensures that the pressure is evenly distributed across the $730 \times 800$ plate, preventing leaks or "flashing" at the edges. Rayshape’s real-time distributed digital dynamic temperature control system further complements this by maintaining the heating furnace at a precise $\pm 1$°C, ensuring the PP sheet is at its optimal flow state. This "high-quality automated equipment" reflects the Elemotion spirit of diligence and self-surpassing excellence. With a 90-set parameter memory, manufacturers can store optimized profiles for different tray depths, ensuring a stable and reliable output even for the most complex geometries. Based in Wenzhou, Rayshape provides seasoned R&D and professional after-sales service, ensuring that global food packaging suppliers can achieve high-volume, low-consumption production with a guaranteed ROI and a hygienic, standardized workflow.
