The Custom Plastic Injection Molding Applications
For products such as smartphone/tablet cases, wireless earbud housings, smartwatch cases, and power bank housings, we use high-strength PC/ABS raw materials for impact and scratch resistance. These materials are paired with processes like nano-coating (anti-fingerprint) and 3D hot stamping (customized appearance). All products comply with the RoHS 2.0 environmental certification, meeting the lightweight and high-aesthetic requirements of consumer electronics. They also help create a differentiated appearance, ensure product durability, and lay the groundwork for the upgrading of consumer electronic products.
For items including control panel housings of rice cookers/microwaves, TV casings, air purifier filter frames, coffee machine bodies, and robot vacuum housings, we adopt high-temperature resistant PP/PS raw materials (withstanding 120-150℃), with spray-painted wear-resistant treatment on the surface. The products have obtained 3C certification. Structural optimization reduces assembly processes and lowers production costs for home appliance manufacturers, while balancing the high-temperature resistance functionality and appearance texture of home appliances, in line with the safety and environmental requirements of household scenarios.
For medical devices such as monitor housings, blood glucose meter housings, infusion pump frames, medical cart panels, and medical testing equipment housings, we select medical-grade PE/PP raw materials (sterilizable and corrosion-resistant), with halogen-free and environmentally friendly surface treatment. All products meet ISO 13485 certification, and their structural design includes reserved disinfection spaces. These features satisfy the strict sterility and disinfection resistance requirements of medical scenarios, ensuring the long-term stable operation of the equipment.
For parts like car central control panel housings, car charger housings, window lift button frames, and trunk storage box housings, we use weather-resistant ABS/PA raw materials (resistant to high and low temperatures of -40~80℃ and UV rays), with wear-resistant coating on the surface. The products comply with IATF 16949 certification. Structural optimization enhances shock resistance, and the components adapt to complex automotive working conditions (high/low temperatures, vibration), ensuring no aging or deformation during long-term use.

FAQs
Safe and qualified plastic components are not only the foundation of product compliance, but also a key support for the implementation of design and the upgrading of your product experience.
1. Strengthen Design Reliability and Reduce Implementation Risks：
Plastic components that meet safety standards (such as RoHS (Restriction of Hazardous Substances) and FDA (Food and Drug Administration) certifications) can accurately match design parameters. This avoids rework of design schemes caused by issues like material brittleness and deformation. At the same time, they directly meet industry compliance requirements, allowing products to pass market access tests without additional adjustments and accelerating the transformation of design achievements.
2. Upgrade User Experience and Enhance Design Credibility：
Fully qualified plastic components do not release harmful substances and have stable physical properties (such as anti-aging and temperature resistance). They not only ensure user safety during use (especially for medical, maternal and infant, and electronic products) but also extend the service life of products. This truly delivers on the design commitments of “durability” and “safety” and enhances users’ trust in the product.
3. Reduce Brand Risks and Safeguard the Long-Term Value of Design：
Inferior plastic components may cause product malfunctions, safety complaints, or even recalls, which directly destroy the brand reputation accumulated through design. However, choosing safe and qualified components can help avoid such risks from the source. This ensures that the sense of quality in product design is continuously conveyed and helps your brand build a reliable image.
