Customized headlight plastic parts moulding

In addition, our company has established cooperative relationships with plastic raw material suppliers, printing manufacturers, etc. to ensure the supply of raw materials and printing quality. Through our rich experience and perfect supply chain, our company can provide customers with high-quality customized customized headlight plastic parts moulding products to meet their specific needs. At the same time, we have 10 years of professional foreign trade service experience, understand the foreign trade process, and better serve our customers. For customized headlight plastic parts moulding products, we can make corresponding plastic parts, which is mainly done through injection molds.

Customized plastic parts for automotive headlights have a core process framework consistent with that of general injection-molded parts, but they have extremely high requirements in terms of optical performance, appearance, regulations and safety. This makes them more complex and strict in terms of materials, molds, processes and verification.

Its core process can be summarized into the following five stages:

Optical and structural collaborative design

Optical design first: First, determine the photometric regulations and light type requirements, and then design the optical surface (lenses, mirrors).

Structural design: Under the premise of meeting optical functions, structural designs such as installation, sealing, and heat dissipation are carried out. The commonly used two-color injection molding integrates the light-transmitting and non-light-transmitting parts into one piece to achieve complex optical patterns. Mold flow analysis must be conducted during the design process to predict and optimize the impact of defects such as weld lines and bubbles on optical performance.

Material and precision mold development

Material selection: For lenses, optical-grade polycarbonate (PC) with high light transmittance and high impact resistance is preferred. Structural components such as lamp housings can be made of high-temperature resistant materials like PC/PBT and PPA.

Mold development: This is the core investment. The mold cavity must be made of ultra-high-precision optical mirrors and special cooling waterways must be adopted to ensure uniform heat dissipation. For complex structures with side holes, a precise lateral core-pulling mechanism needs to be designed.

High-precision injection molding and process control

The parts of the headlights are extremely sensitive to the manufacturing process. Take PC lampshades as an example. The raw materials must be thoroughly dried (such as being baked at 120℃ for 4 hours), and the injection molding temperature and pressure need to be precisely controlled in sections.

For thick-walled lenses, advanced processes such as multi-layer injection molding can be adopted to significantly shorten the cycle and reduce defects.

Necessary surface treatment

Lenses usually need to be coated with anti-reflection films to increase light transmittance and undergo surface hardening treatment to prevent scratches.

The interior of the reflector bowl/decorative ring needs to be vacuum aluminized to form a reflective surface, and the exterior may be decorated by spraying, electroplating, etc.

Extremely rigorous testing and verification

This is the key to ensuring driving safety. In addition to size and appearance inspection, the following must be carried out:

Optical performance test: Professional equipment is used in a darkroom to detect whether the light distribution complies with the national standard/European standard.

Environmental reliability testing: including high and low temperature cycling, constant damp heat, UV ultraviolet aging, water and dust resistance (such as IP67), etc.

�� Key points and suggestions

Partner selection: It is essential to choose a supplier with successful cases in the automotive lighting industry. They not only need to have precision mold and injection molding capabilities, but also possess full-process experience in optical design, testing and engineering problem-solving.

Cost and cycle understanding: The mold cost and development cycle of headlight parts (usually over six months) are much higher than those of ordinary parts. Thorough communication and design verification in the early stage are the keys to avoiding repeated modifications in the later stage and controlling the total cost.
