During the 10-15 years of development of China's mold industry, those enterprises that pay attention to mold quality and quality management have achieved rapid development. Shangchen is one of these enterprises. Its unremitting pursuit of high-quality molds and high-level company management has changed the concept of "low quality" of molds made in China by many buyers at home and abroad, While many enterprises of the same type have developed and expanded, Shangchen has achieved a qualitative leap and reached a level equivalent to or even better than that of the European plastic mold industry.

Quality Control

As a mold enterprise with superior quality, Shangchen has a strong management and quality inspection team. From the three-dimensional drawing of the mold to the first mold test, it has very strict analysis and quality control.

3D Design Analysis

After receiving the customer's product design, the project manager will immediately convene all relevant technicians to analyze its shortcomings and possible problems in the processing process. For example, analyze the demoulding slope, strength, plastic filling, deformation, wall thickness, skin texture, etc. After these discussions, the module flow analysis will be carried out immediately. If there are any problems, the customer will be contacted immediately and solutions or suggestions will be provided.

New Model Conference

After the mold is designed, the design review department reviews the design, including mold structure detection, mold action and guidance system detection, mold injection system detection, mold cooling system detection, mold ejection system detection and mold vulnerable parts detection. All relevant personnel will participate in the technical meeting of new mold design and put forward all technical points, such as the adoption of steel for mold parts, the basic structure of mold, plastic material and its melt index, special requirements of customers, parameters of injection molding machine and processing steps of parts, etc. After the mold design is confirmed by the customer, the steel material shall be sampled and tested with high-quality testing instruments to ensure that there are no cracks or impurities, and the steel hardness tester can measure whether the hardness of the steel material is qualified or consistent.

Mold Processing

Basic quality control of steel materials will also be carried out in the process of die processing of automobile interior parts. Processing is divided into three steps: ① rough machining; ② Semi finish machining of some precision molds; ③ High speed milling finishing.

Quality Control

It has three coordinate measuring instrument and projection measuring instrument, which can measure the dimensions of the mold cavity, core and other parts. After the mold is processed, the three coordinate measuring instrument and other dimension measuring equipment are used to control the dimensions. The qualified ones will be sent to the assembly workshop, otherwise the mold will be reprocessed. Before the first mold test, the quality inspection personnel and the project manager will carry out quality control on the mold assembly, and the mold will be disassembled for inspection by the quality inspection department according to the mold test standard. If it is unqualified, the mold test is not allowed. With special machines for mold testing, the mold testing team has rich testing experience. Their responsibility is to find out the shortcomings of the mold and provide solutions. After that, the mold will be repaired and simulated production will be carried out for a long time before shipment. Important materials such as mold design, drawings, various inspection records, work logs, inspection reports, mold test videos and mold operation manuals will be sent to customers regularly during mold processing.
