Application Scenarios of Hard Plastic Molds

Hard plastic molds are widely used in fields requiring high product strength, precision, and durability, playing a crucial role, especially in the automotive, electronics, industrial equipment, and medical industries.

1. Automotive Manufacturing:

Used to produce structural components such as dashboard frames, headlight housings, heat-resistant engine components, and bumper liners.

Materials are mostly PC/ABS and PA+GF. Molds must possess high rigidity and thermal stability to withstand the high-temperature, high-pressure injection molding environment.

For example, lightweight components such as battery pack housings and electronic control unit housings in new energy vehicles rely on high-precision rigid molds to achieve one-piece molding of complex structures.

2. Electronics and Consumer Devices:

Manufactures high-gloss or high-strength housings for smartphone frames, laptop shells, routers, and smart speakers.

Mold cavity precision reaches ±0.02mm, and the surface is mirror-finished to ensure a flawless appearance and dimensional stability.

3. Industrial and Electromechanical Equipment:

Used for producing high-strength engineering plastic parts such as motor covers, pump bodies, connecting flanges, and circuit breaker assemblies.

Common materials include PBT, PPS, and PEEK, requiring high temperature resistance and corrosion resistance. Mold steel is selected from H13 or S136H to improve wear resistance and fatigue resistance.

Sunny Optical developed a miniature lens holder mold for VR devices with a cavity size of only 2.5mm × 1.8mm and a dimensional tolerance of 0.001mm, demonstrating its extreme precision manufacturing capabilities.

4. Medical and Health Equipment:

Used in medical devices requiring high cleanliness and precision, such as blood glucose meter housings, ventilator components, and endoscope handles.

Molds must comply with GMP standards, employ aseptic design, and have optimized flow channels to reduce residue, ensuring product sterilability and biocompatibility.

5. Packaging and Containers:

Produces rigid plastic bottles, turnover boxes, food-grade containers, etc., requiring safe materials and robust structures.

For example, PET preform molds and PP pharmaceutical packaging boxes can achieve high transparency and good sealing performance through injection molding and blow molding processes.

Qingdao Xueyu Molding Products Co., Ltd. is mainly engaged in the design and manufacturing of injection molds, injection molding and secondary processing (spraying, pad printing, ultrasonic welding, stamping), etc. For more information about hard plastic molds, please contact us.
