Products Description
This series of precision plastic parts are made of high-end engineering-grade, medical-grade and food-grade plastic materials including POM, PA66, ABS, PC, PEEK, PTFE and PMMA, with pure material, no impurities or bubbles and dense internal structure. Adopting precision closed-loop injection molding and five-axis CNC precision carving technology, it can process complex plastic parts with micron-level tolerance, ultra-thin wall, special-shaped curved surface and hollow nested structure, with a minimum forming size of 1mm³ to meet the needs of micro-precision equipment accessories. Finished through deburring, mirror polishing, sandblasting and hardening treatment, the products feature smooth surface, no shrinkage dents, no warping deformation and high dimensional consistency. Customizable properties such as insulation, flame retardancy, wear resistance, temperature resistance and aging resistance are available, supporting insert embedding, two-color molding and soft-hard composite integrated processing. With tiny deformation rate and high assembly fitting degree, the parts are not easy to loosen or wear during long-term operation, adapting to high-demand working conditions such as high-frequency assembly, dynamic fine adjustment, closed limit and insulation protection of precision equipment.

Product Advantages
Micron-level high precision for zero-error assembly
Adopting high-precision mold and CNC processing technology, the dimensional tolerance is controllable within ±0.01mm with excellent batch consistency. It completely eliminates defects of ordinary plastic parts such as dimensional deviation, warping deformation, assembly jamming and excessive gaps, meeting the strict assembly standards of high-end precision equipment.
Free forming of complex structures with high design flexibility
Breaking the structural limitations of traditional plastic parts, it supports integrated forming of thin-wall, hollow, special-shaped curved surface and nested composite structures without secondary splicing. The integrated structure is more stable, satisfying customized structural requirements of various non-standard, micro and precision equipment.
Customizable physical properties for full working condition adaptation
A variety of high-end engineering materials are optional, realizing differentiated performances such as insulation & flame retardancy, super wear resistance, low friction, high & low temperature resistance, corrosion resistance, food grade and medical cleanliness. It adapts to harsh working conditions in electronics, medical treatment, new energy and precision instrument industries.
Lightweight & high strength for cost reduction and efficiency improvement
Compared with metal parts, precision plastic parts are lighter in weight, rust-free and noise-free during operation, with excellent structural rigidity and fatigue resistance. They are not easy to break or wear under long-term reciprocating and fine adjustment conditions, effectively reducing equipment weight and overall production costs while improving operational stability.
Integrated molding without secondary processing for high cost performance
Finished products meet high-precision appearance and functional requirements directly without complicated secondary processing such as polishing and trimming. Featuring high production efficiency and stable yield, it supports small-batch sample customization and large-scale mass production, with higher comprehensive cost performance than ordinary plastic and metal parts.

Product Q&A
Q: What is the difference between precision plastic parts and ordinary plastic parts?
A: Precision plastic parts are made of high-end engineering plastics and high-precision molds, with extremely small dimensional tolerance, no burrs and no deformation. Their batch consistency, accuracy, strength and stability are much higher than ordinary plastic parts, suitable for precision equipment assembly. Ordinary plastic parts have poor accuracy, many defects, and are easy to deform and age, only suitable for simple scenarios and unable to meet precision working condition requirements.
Q: What about the durability and stability of precision plastic parts?
A: Made of high-purity engineering plastic raw materials and formed by precision injection molding, the products have compact structure, excellent fatigue resistance, deformation resistance and aging resistance. They are not easy to crack, loosen or fail after long-term high-frequency use. With stable temperature resistance, corrosion resistance and insulation performance, the batch quality is unified with a qualification rate of over 99.5%, suitable for long-term industrial precision working conditions.
Q: Can special properties such as anti-static and high temperature resistance be customized?
A: Yes. According to the service temperature, medium and working environment, we can select high temperature resistant materials such as PEEK, PC and PA, and support special performance modifications such as anti-static, flame retardant, high wear resistance, UV resistance, food grade and toughening to match harsh application scenarios.
