Fine "making" water tray: how to create a "leakproof" invisible guardian of air conditioning through precision mold and process control.

The water collection tray is the cornerstone of air conditioner reliability, and its quality directly affects the product's lifespan and user safety. Top manufacturers are taking this "invisible" component to the extreme through precision manufacturing, materials science and systems thinking.

• The precision of the mold determines the precision of the product: High-quality water collection trays start with high-precision molds. The mold cavity with mirror polishing technology and nano-coating can ensure that the surface of plastic parts is as smooth as a mirror, fundamentally eliminating the adhesion and residue of condensation water caused by surface roughness and improving the drainage efficiency. Meanwhile, the precisely arranged conformal cooling water channels within the mold can significantly shorten the injection molding cycle and reduce the internal stress of the product, thus avoiding deformation in the later stage.
• Materials Science and Functional Integration: In addition to the common flame-retardant ABS, the application of high-performance engineering plastics such as ASA and PPE in harsh environments (such as high temperature and high humidity, and chemical corrosion) is increasing day by day. In addition, through the "in-mold embedding" technology, electric heating wires, water level sensors, etc. can be directly embedded into the plastic parts, achieving intelligent functions such as anti-freezing and overflow alarm, and enhancing the added value of the products.
• Full-process quality fortress: From the drying of raw material particles, closed-loop control of injection molding process parameters (temperature, pressure, speed), to 100% air tightness testing (using differential pressure method or flow method) and load testing, a reliable quality defense line has been established at each link. Providing complete material certification reports (such as UL94 V-0) and performance test data has become a necessary condition for winning the trust of international first-line brand customers.
