For Pmma Resin Pellets Injection Moulding, Ningbo (P&M) Plastic Metal Products Co., Ltd. has 18 years of mold manufacturing technology and 10 years of export experience. We provide professional one-stop customized mold services and are a professional plastic mold manufacturer. We can use injection molding, blow molding, die-casting, and rotational molding.
MMA resin particle injection molding is a plastic processing technology that uses high-purity PMMA resin particles as raw materials to complete the physical molding process of "heating and melting → high-pressure injection into the mold cavity → pressure maintenance and shrinkage → cooling and solidification → demolding and part taking" in an injection molding machine, ultimately obtaining PMMA products that are completely consistent with the mold cavity, have high transparency, high surface gloss, and complex structure.
1. Raw material pretreatment: drying and dehydration are the core
PMMA resin particles have a certain degree of moisture absorption (water absorption rate of 0.3% -0.4%, higher than PP and PE), and moisture can cause defects such as "bubbles, silver wires, and surface fogging" during injection molding. Therefore, drying treatment is the core of pretreatment.
2. Injection molding machine and mold preparation: adapted to PMMA characteristics
PMMA injection molding has higher requirements for equipment and molds than ordinary plastics, and requires targeted selection and design.
3. Melt injection: precise control of temperature and pressure
PMMA melt has high viscosity and poor thermal stability, and requires "gradient temperature control+segmented injection" to ensure uniform melting and no degradation.
Material barrel temperature setting (core parameter, directly affecting melting quality):
4. Pressure holding and cooling: control shrinkage and dimensional accuracy
Pressure holding and cooling directly affect the shrinkage rate, internal stress, and dimensional accuracy of the product, and require precise matching.
5. Demoulding and retrieval: Protecting appearance and structure
PMMA products have a smooth surface but limited toughness. Attention should be paid to the demolding method and the strength of the parts to avoid scratches or damage.
6. Post processing and testing: optimizing performance and ensuring compliance
The post-processing process for PMMA products is simple, but strict testing is required for appearance and performance.

PMMA resin particle injection molding, with its advantages of "high-end appearance, controllable performance, and lightweight", has penetrated into various fields such as consumer electronics, automotive, lighting, home furnishings, and optics, becoming the core molding technology for high-end products
1. In the field of consumer electronics: the core choice for high-end exterior components
Consumer electronics have extremely high requirements for "appearance texture, lightweight, and precision structure", and PMMA injection molding is the mainstream solution.
2. Automotive field: Lightweight and weather resistant exterior functional components
PMMA injection molded parts used in the automotive industry focus on "lightweight replacement of glass, weather resistance and impact resistance", mainly applied in:
Automotive lighting system: used for front headlight lampshades (high transparency+weather resistance, long-term outdoor use without yellowing), taillight housings (colored PMMA, uniform transparency), interior ambient light lampshades (high gloss, enhancing interior grade);
Automotive interior parts: used for dashboard panels (transparent or semi transparent, compatible with display screens), center console decorative strips (coated to enhance metallic texture), door interior panels (lightweight, reducing body weight);
3. Lighting field: dual requirements for optical performance and appearance
The lighting industry relies on PMMA's "high transparency+weather resistance", which is one of the core application scenarios for PMMA injection molding:
LED lighting fixtures: used for LED ceiling lampshades (light transmittance ≥ 90%, uniform light without glare), tube lamp housings (white or colored, high gloss), and courtyard lamp lampshades (weather resistant modified, outdoor for 5 years without aging);
Special lighting: used for stage lamp covers (high-temperature modified, long-term use without deformation), emergency lamp housings (impact resistant, drop 1.5m without damage), and automotive atmosphere wicks (precision structure, suitable for narrow spaces).
4. In the field of home and daily necessities: a balance between aesthetics and practicality
PMMA injection molded parts in the home field focus on "beautiful appearance, durability and easy cleaning", mainly used for:
Home decor: Used for acrylic vases (transparent as crystal, high-end texture), photo frame frames (customized in color, suitable for different decoration styles), storage boxes (semi transparent, easy to view internal items)
5. Optics and Medical Fields: Strict Requirements for Precision and Safety
In fields with strict requirements for accuracy and safety, PMMA injection molding also occupies an important position:
Medical field: used for medical equipment panels (alcohol resistant wiping, easy to clean and disinfect), syringe windows (high transparency, easy to observe medication), dental braces (transparent and invisible, beautiful and comfortable, in compliance with medical grade safety standards)
