Auto interior custom 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 auto interior custom 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 auto interior custom plastic parts moulding products, we can make corresponding plastic parts, which is mainly done through injection molds.

Phase One: Precise Demand Definition and Synchronous Engineering

This is the cornerstone of the project, aiming to "get it right the first time".

Deep demand freeze: Clearly define the safety requirements of the parts (flame retardancy, volatile organic compounds (VOC), odor), sensory quality (high gloss/matte/leather texture on the A side, touch, gap surface difference), regulatory standards and cost targets.

Synchronous engineering and CAE analysis: The engineering team of the mold supplier must get involved early to conduct manufacturability design analysis and use CAE mold flow analysis software for simulation. This can predict and solve defects such as insufficient filling, weld marks, shrinkage and warping deformation in advance. For instance, A study on the interior panels of the A-pillar, through orthogonal experiments and optimization, found that the melt temperature and holding pressure have the greatest impact on warpage, and determined the optimal parameter combination.

Material science selection: Interior materials need to take into account strength, heat resistance, aging resistance, low odor and good surface performance.

Basic structural components: Commonly used modified PP (such as PP/EPDM) and ABS, which have low cost and good toughness.

High-gloss/high-demand appearance parts: Use PC/ABS alloy or high-gloss ABS.

Emerging processes: Low-pressure injection molding is used to directly coat plastic onto fabrics or leather, achieving a more advanced touch.

Phase Two: High-complexity mold Engineering and process Development

Interior parts molds are a manifestation of technology-intensive nature.

Mold design features

Hot runner system: Large interior parts commonly use hot runners to save raw materials and stabilize quality. For long strip-shaped parts (such as B-column trim plates), a sequence valve hot runner is used to control the melt flow sequence and balance the filling.

Complex demolding mechanism: Interior parts often have upside-down and snap fasteners, and the mold needs to integrate multiple core-pulling mechanisms such as inclined tops, sliders, and hydraulic cylinders. For instance, the B-column decorative panel mold adopts a variety of combined demolding mechanisms such as T-slot sliders and inclined core-pulling.

High-efficiency temperature control system: It adopts conformal cooling water channels or rapid thermal circulation technology to enhance surface quality, eliminate weld marks and shorten the cycle.

Process development and validation: Based on the CAE analysis results, mold trials are conducted, and the process parameters (such as melt temperature, mold temperature, injection speed, holding pressure and time) are precisely adjusted using the experimental design method to achieve the best appearance and minimum deformation. Subsequently, it must pass strict dimensional measurements, appearance reviews, as well as environmental (high and low temperatures, sunlight exposure) and durability (wear and tear, insertion and extraction) tests.

Phase Three: Statistical process control, mass production and delivery

Ensure that the first item is consistent with the one millionth item.

SPC mass production: During mass production, key process parameters (such as injection time and pressure) and critical product dimensions are monitored and statistically analyzed in real time to achieve preventive quality control.

Full-chain traceability and zero-defect delivery: Establish a complete traceability system from raw material batches to finished products. Appearance parts usually need to undergo 100% full inspection and be delivered in custom protective packaging.
