Auto Headlight Holder Plastic Mold Design Considerations
——
1. Mold material selection for auto headlight holder plastic mold
The first step in designing an auto headlight holder plastic mold is selecting the appropriate mold material. The mold material must meet the characteristics of the plastic material and the requirements of the molding process. Generally, hot-work and cold-work mold steels are preferred materials due to their excellent wear resistance, corrosion resistance, and thermal conductivity. These properties not only extend the headlight auto lamp housing plastic mold's lifespan but also improve production efficiency.
2. Auto headlight holder plastic mold structure design
The structural design of headlight auto lamp housing plastic molds is crucial for the molding process and the quality of the final product. A typical auto headlight holder plastic mold includes a molding section, gating system, venting system, cooling system, and ejection system. During the design process, comprehensively considering the headlight auto lamp housing plastic mold's opening and closing mechanism, parting surface, and cooling channel layout is key to ensuring efficient auto headlight holder plastic mold operation and the production of high-quality parts.
3. Mold cooling system design for auto headlight holder plastic mold
The headlight auto lamp housing plastic mold's cooling system directly impacts product quality and production efficiency. Uniform mold temperature is guaranteed by a well-designed cooling system, which also reduces the molding cycle and stops the thermal degradation of the plastic material caused by excessive temperatures. Thus, in the design stage, great thought has to be given to the placement and design of cooling channels in order to maximize general production efficiency and enable fast molding.
4. Gating system design for auto headlight holder plastic mold
The gating system is one of the core components of an headlight auto lamp housing plastic mold, consisting of the main runner, branch runners, and gate. A good gating mechanism guarantees that the plastic material swiftly and uniformly fills the mold cavity, therefore producing the required component. Material flowability, filling time, and holding time have to be taken in the design to guarantee product quality.
5. Venting system design for auto headlight holder plastic mold
During injection molding, air within the mold cavity needs to be promptly vented to prevent bubble formation or interference with plastic flow. An effective venting system design includes planning the location and size of venting channels to ensure smooth gas discharge while maintaining headlight auto lamp housing plastic mold strength and rigidity.
Specify the type of plastic (e.g. PP, ABS) and post-processing requirements (e.g. spraying, silk-screen printing), and provide 2D or 3D plastic part drawings should be provided. At the same time, provide the production volume, appearance requirements, tolerance standards, etc.
Generally speaking, our engineers will start to prepare the quotation immediately after the customer provides the complete production requirements. Usually it takes about 1-3 days.
The lead time for regular injection molds is usually 30-60 days, and may be longer for complex molds. For example, the typical lead time for liquid silicone molds is around 60 days, covering design, manufacturing, mold testing, etc.
High-precision processing technology: High-precision equipment such as CNC machining centers (CNC) and electric discharge machining (EDM) are used to optimize the design process in combination with CAD/CAM software. Quality control: Inspection of key dimensions of the mold by Coordinate Measuring Machine (CMM) and verification of multiple sample batches during the trial molding stage. Material Selection: Use die steel with high wear resistance (e.g. H13, S136) and surface treatment (e.g. nitriding, chrome plating) for die nuts to extend the life.
After every 50,000 molds, check the guide pillar, ejector pin and other wear parts, and clean up the residual plastic and rust on the mold surface. Use high temperature grease for sliding parts (e.g. tilt top, slider) to reduce friction loss. Ensure that the water circuit is smooth and the temperature difference is ≤5℃ to avoid cracking of the mold due to thermal stress.
Mould cost of materials accounted for about 30-40% (such as 1 ton of P20 steel price of about 20,000 yuan), processing costs accounted for more than 50% (CNC labor hourly rate of about 80-150 yuan / hour). Small batch production can choose aluminum mold or simplify the structural design; more than 100,000 pieces is recommended to use carbide inserts to enhance life!
Mould injection products need to fully meet the design requirements (such as size, appearance), and can be continuous and stable production. Mold marking, inspection reports (such as material hardness test) and engineering drawings should be complete.
Mould steel (such as S136H, NAK80 and other imported materials cost more) and the type of mold embryo (aluminum mold short-term cost is low but short life) directly affect the cost, the use of CAD/CAE/CAM design technology, hot runner system, etc. will increase the upfront investment, but can enhance the long-term benefits (such as reducing the sprues, increase production capacity).
