Analysis of the manufacturing process and quality control points of high-precision automotive molds

The manufacturing process of high-precision automotive molds is complex and delicate, and the quality control points are also extremely critical. The following is a detailed analysis of its manufacturing process and quality control points:

1. Manufacturing process of high-precision automotive molds

Design
Determine the structure and details of the mold, including the size, shape, material and processing technology of the mold.

The designed mold needs to meet the requirements of the customer and the use environment, while ensuring the quality and performance of the mold.

Raw material procurement
According to the design requirements, select high-quality and stable mold materials.

Strictly inspect the purchased materials to ensure that the materials meet the requirements.

Manufacturing
The process of converting the design drawing into an actual mold, including mold casting, processing and welding.

When casting, it is necessary to ensure that the molten metal is poured evenly and the product obtained after cooling is defect-free.

When processing, use advanced processing equipment and tools, such as CNC machining centers, lathes, milling machines and grinders, to precisely process the mold.

When welding, use appropriate welding technology to ensure the assembly and repair quality of the mold.
Processing
The mold is milled, cut, ground and polished to obtain the required shape, size and surface roughness.
The processing process must strictly follow the processing technology specifications to ensure the accuracy and quality of mold processing.
Assembly
The various components of the mold are assembled, analyzed and inspected to determine the exact position and fit of each component.
Adjustment and calibration are performed to ensure that the mold can operate normally.
Debugging
A series of tests are performed on the mold to determine whether its performance and function are good.
If problems are found, the mold is adjusted and optimized until it meets the customer’s requirements.

2. Key points of quality control of high-precision automotive molds
Data management
Effective product data management, process data management, and drawing document management are carried out to ensure the comprehensiveness of the files, consistency of drawing versions and effective sharing.
Consistency check
Through effective, meticulous and strict testing methods, the consistency and integrity of mold drawings, processing technology and physical data are ensured.
Cost control
The manufacturing cost of the mold is reduced by effectively controlling the issuance of work tickets in the workshop, managing the scrapping of tools, and accurate mold structure design, efficient mold parts processing and accurate spare parts testing.
Overall planning
Organize and integrate information such as planning, design, processing technology, workshop production conditions, and human resources to coordinate planning and production effectively, ensure mold quality and deliver on time.
Production management system
Develop a complete mold production management system to realize computer information management of mold production management processes, including mold production plan formulation, mold design, process formulation, workshop task assignment, and product inspection.
Failure mode and impact analysis
Establish a mold design and manufacturing failure mode and impact analysis library to prevent the same problem from recurring.
Processing technology preparation
Prepare processing technology to ensure that relevant resources can be in place in a timely manner, and specifically associate quality with individuals based on the upper and lower process records.
Standards and operating instructions
Develop mold design standards, mold design operating instructions, mold manufacturing standards, and mold manufacturing operating instructions suitable for the company and customers to standardize mold design and mold manufacturing processes.
Supply chain management
Standardize procurement, warehouse management, production order placement, material in and out of the warehouse, tool damage reporting, and delivery management processes to streamline the material supply chain and prevent production disconnection.
Training and Assessment
Regularly train and assess mold design and mold manufacturing personnel to improve their professional skills and sense of responsibility.
Project Follow-up Management
Establish a mold project follow-up management team to ensure smooth communication and supervision with customers, marketing, engineering, procurement, manufacturing, warehouse and other departments to save costs and time.
In summary, the manufacturing process of high-precision automotive molds includes design, raw material procurement, manufacturing, processing, assembly and debugging, and the key points of quality control involve data management, consistency inspection, cost control, overall planning, production management system, failure mode and effect analysis, processing technology preparation, standards and operating instructions, supply chain management, training and assessment, and project follow-up management. These key points together constitute the quality control system for high-precision automotive mold manufacturing, ensuring the quality and performance of the mold.
