Quality Concept

Concept guides people's behavior. Shangchen pays attention to constantly updating the quality concept of team members in the management process, so as to complete the quality control of multiple work links. In Shangchen, people know that quality is the basis of survival and development, and managers have a high standard of quality concept.

Quality Standard

All the work of injection mold manufacturers must refer to quality standards in practice, and design and manufacture molds according to these quality standards. The quality standards include: plastic mold design standards, plastic mold processing standards, plastic mold installation standards, plastic mold inspection standards, etc. under the influence of the strong executive ability of the team, the quality standards have penetrated into the work of every employee.

Quality Control

Shangchen has its own perfect production and management system, and has quality monitoring in every production link. We try our best to avoid mistakes and curb the expansion of existing mistakes. Its scope is: from the design structure of plastic products to the feasibility of mold structure design, from mold raw material procurement to raw material testing, from the selection of raw material processing technology to part quality testing, from part assembly to overall mold testing, and so on. There are corresponding charts in each step, and each link shall ensure zero defects as far as possible, so as to finally ensure the high quality of mold delivery.

Design Test

We will conduct a comprehensive analysis and inspection on any product design provided by Shangchen or customers, such as the possibility of plastic molding process, plastic mold structure operation and matching of relevant parts. These can effectively avoid the mold repair work and cost caused by product design defects. We believe that if we spend more than 10 minutes on product design, we can save one month in mold production. Through the accurate analysis of mold design, processing steps and the application of plastic mold structure, it provides customers with the most perfect solution. Mold inspection involves many aspects, such as mold strength, mold flow analysis, mold injection molding, cooling system, guiding system, specifications of various spare parts, selection of customers' machines and customers' special mold requirements, all of which should be tested according to mold design standards.

Inspection Of Purchased Steel

The purchase of spare parts has strict inspection process and time control, component standardization, dimensional accuracy, steel hardness and material flow inspection, etc.

Process Quality Control

The dimension shall be strictly controlled. After each part is processed, it shall be tested according to the mold design, and the tolerance shall be controlled. The next part can be processed only after each part meets the standard. Before NC milling, all programs must be strictly checked. After completion, we will test the accuracy of each component with a CMM. We have a lot of testing: professional processing technology and machine maintenance training; Self inspection of processed workpieces and acceptance of quality department; Reasonable overtime system and tooling control system.

Installation Quality Inspection

Complete inspection of plastic molds to ensure the continuity of mold structure and the standardization of parts. The project manager and quality inspection personnel shall inspect the plastic mold according to the company's standards, so as to ensure the quality of products. Once problems are found, they can be corrected immediately and errors can be effectively prevented. In addition, we continuously test the cooling system, hydraulic oil duct system and hot runner system of plastic molds. The quality inspection department shall submit the inspection report within 24 hours after the mold inspection. The report shall include product size, appearance, injection parameters and physical parameters. We use different inspection standards and tools for different products. In the testing room, the quality inspection department will test the high-pressure injection molding machine, high-speed injection molding machine and automatic operation device, and then provide modification suggestions for the modification of defective products. We have accumulated rich experience in the field of plastic molds, which has laid a foundation for better providing solutions for customers. With the continuous upgrading of testing equipment, our product inspection has become more and more professional and reliable.

Die Test

To a certain extent, we test the mold only to find out the problems existing in the mold, not to solve the problems. Therefore, the mold test is divided into several steps, including empty operation, high-pressure holding, high-speed injection and related long-time mold operation test.

Pre Shipment Inspection

According to the order documents, customer requirements and company standards, we will conduct strict acceptance inspection on the mold. These order documents together with other inspection reports must be filed before the mold is shipped.

Project Processing Department

The technicians of the processing department should review the drawings before processing the mold materials to ensure that the mold can be shipped in a reasonable and shortest time, which can not only shorten the production cycle, but also solve the waste of raw materials.

Project Progress Department

The employees of the process department must track the processing progress of the mold every day, take photos of each processing step of the mold and file it, and then make it into a report in order to provide the mold process report to the sales department.

Project Process

The business department directly contacts with customers and discusses technical issues. The independent responsibility system of project manager and salesman ensures the accuracy of project implementation and clear responsibilities. Detailed and complete documents for customer file management can also find omissions and solve problems in time. The project department is directly in charge of the project department and the quality control department to ensure the delivery date and quality of each mold. Follow up each order process, control the process to a specific time, and seize the time to implement the task. Each technical meeting will ensure the good design scheme and processing technology of the die. The process department controls each processing detail. The company has its own technical and cultural training. Every year, the company invests a lot of R & D funds and achieves fruitful results in the field of R & D. In order to improve the continuity of order management, regularly train the sales department, project department, production department and quality inspection department. The purpose is to improve the professional skills of employees so that everyone can supervise the quality of molds.
