The manufacturing and molding of custom automotive parts is an extremely rigorous and complex process, representing the highest standards in the plastic processing industry. Its core is far more than just the act of "injection molding", but a management system that runs through the entire life cycle of design, engineering, production and verification, ensuring that every part meets the automotive industry's ultimate requirements for safety, durability, precision and consistency.
The following is a detailed manufacturing and forming process for custom automotive parts, strictly adhering to industry standards such as IATF 16949.
The entire process of custom automotive parts manufacturing and forming
Phase One: Preliminary Quality Planning and Design - A Blueprint for Success
This is the most crucial stage, aiming to "get it right the first time".
Demand Input and feasibility analysis
Functional requirements: Installation position of parts, load, resistance to high and low temperature cycles (-40℃ to over 120℃), oil resistance, chemical solvent resistance, aging resistance, etc.
Dimensions and accuracy: Based on the GD&T drawings of the original equipment manufacturer, understand the strict dimensional tolerance requirements.
Appearance requirements: There are different surface treatment standards for the A surface (exterior parts, such as grilles), B surface (visible interior parts), and C surface (invisible parts).
Safety and regulations: Flame retardancy (such as UL94 V-0), low volatile organic compounds (VOC), odor, etc.
Product Design Optimization and DFM
Core collaboration: The engineering team of the parts supplier works deeply with the original equipment manufacturer/Tier 1 supplier.
CAE Analysis
Structural analysis: Ensure the strength and rigidity of the parts under conditions such as vibration and shock.
Mold flow analysis: Crucial! Before mold opening, simulate plastic filling, cooling, shrinkage and warpage, accurately predict and solve potential shrinkage, cavitation and weld line problems, and optimize the gate and cooling system.
Material selection
Bumper, dashboard: PP+EPDM-T20 (impact-resistant, low-temperature resistant).
Engine periphery: PA66-GF30 (high strength, high heat resistance).
Interior parts: ABS, PC/ABS (good comprehensive performance, easy to spray).
Headlamp lens: PC (high transparency, high heat resistance).
Key point: The materials must come from the supplier list approved by the original equipment manufacturer and have complete material certification.
Phase Two: Precision Mold Design and Manufacturing - Creating the "Mother Body"
Automobile molds are a model of heavy assets, high precision and long service life.
Mold design
Steel: High-grade and highly wear-resistant die steel (such as P20, 718, S136) is selected and heat-treated.
Hot runner system: Standard configuration. The needle valve type timing control of the hot runner is adopted to achieve balanced filling, reduce waste and internal stress.
Cooling system: Design conformal cooling waterways to maximize cooling efficiency, ensure stable cycles and consistent dimensions.
Action mechanism: Complex sliders, inclined tops and hydraulic cylinders, used for handling upside-down and threaded structures.
Exhaust system: A precise exhaust slot is indispensable to prevent charring.
Precision machining and assembly
The die core is processed by using processes such as gantry CNC, precision electrical discharge machining, and slow wire electrical discharge machining.
The cavity surface undergoes specified treatments: mirror polishing (for headlights), etching (for interior leather textures).
The mold assembly and debugging are completed by senior fitters.
Phase Three: Mold testing and process Validation - Approaching Perfection
Through repeated debugging, the best production process is locked in.
Mold trial stage
T0 Mold test: Initial debugging, checking the basic shape and filling.
T1... Tn mold test: Based on the measurement and evaluation results, optimize the mold and process until the sample is qualified.
Sample evaluation and measurement
Dimensional measurement: Use a three-coordinate measuring machine for full-size measurement, compare it with CAD data, and issue a report.
Appearance review: The quality engineer of the original equipment manufacturer reviews the standard parts under standard light sources.
Performance and durability testing
High and low temperature cycling test
Vibration test
Chemical reagent resistance test
UV aging test
Production part approval procedure
Before mass production, the supplier must submit a complete PPAP file package to the customer, including design records, process flow diagrams, control plans, performance test reports, etc., and obtain the customer's formal approval.
Phase Four: Mass Production and Process Control - Absolute Stability
Make sure that the first item is exactly the same as the one millionth item.
Standardized production
The operator strictly follows the operation instruction manual.
The mechanical hand automatically picks up the items to prevent human damage.
Statistical Process control
Real-time monitoring and recording of key process parameters (injection time, peak pressure, etc.).
Conduct frequent spot checks on the key features of the products, input the data into the control chart, and achieve predictive management and control.
Error Prevention and Traceability
Adopting error-proofing technology to prevent missed installation and incorrect installation.
100% traceability: Each part or batch can be traced back to the production time, equipment, raw material batch and process parameters.
Phase Five: Delivery and Continuous Improvement
Shipment inspection: Inspection is carried out in accordance with the AQL sampling standard.
Packaging and delivery: Use custom scratch-resistant packaging and deliver to the final assembly line of the original equipment manufacturer on time.
Continuous improvement: Apply methods such as 8D to address quality issues and carry out lean production activities to optimize efficiency.
