In the 10-15 years of the development of China's mold industry, thoseenterprises that pay attention to mold quality and quality management have achieved rapid development, JMJT is one of these enterprises, the unremitting pursuit of high-quality molds and high-level company management, and in the development and growth of many similar enterprises, JMJT has achieved a qualitative leap in 202. To reach the European mold industry quality equivalent or even better level.
Three-dimensional design
After receiving the customer's product design, the project manager will immediately call all relevant technical personnel to analyze its shortcomings and possible problems in the process of processing. For https://fanyi.youdao.com/downloadexample, the release slope, strength, plastic filling, deformation, wall thickness, skin grain analysis. At the end of these discussions, a mold flow analysis is carried out immediately, and if any problems arise, the customer is immediately contacted with solutions or suggestions.
New Mold Meeting
When the mold is designed, the design audit department reviews the design, including mold structure testing, mold action and guidance system testing, mold injection system testing, mold cooling system testing, mold ejection system testing, mold vulnerable parts testing. All relevant personnel will participate in the new mold design technical meeting, put forward all the technical points, such as: the use of mold parts steel, the basic structure of the mold, the plastic material and its melting index, the special requirements of customers, parameters and parts of the processing steps. After the design of the mold is confirmed by the customer, the steel material is 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
Quality control
There are three coordinate measuring instrument and projection measuring instrument to measure the cavity, core and other parts of the mold. After the mold is processed, the coordinate measuring instrument and other measuring equipment are used to control the size. 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 project manager will carry out quality control on the mold assembly.
The mold will be disassembled for inspection by the quality inspection Department according to the mold test standards. If it is not qualified, it is not allowed to test the mold. With a special machine for mold testing, the team has rich experience in testing. Their duty is to find out the shortcomings of the mold and provide solutions. After that, the mold will be repaired, and the simulation production will be done for a long time before shipping. Such as mold design, drawings, various inspection records, work logs, inspection reports, trial videos and mold operation manuals and other important materials will be sent to customers regularly during mold processing.
JMJT ranks among the top mold manufacturers in China, and has gained a unique advantage in the molding market.
JMJT has a rigorous mold manufacturing process, is famous for hundreds of special mold structures, and provides customers with advanced technical solutions. And we have established good relations with mold manufacturers at home and abroad, and provide consulting services.
Quality control
JMJT has its own perfect production and management system, and has quality control in every production link. We do our best to avoid the occurrence of mistakes, and to prevent the expansion of existing mistakes. Its scope is: from the design structure of the product to the feasibility of the design of the mold structure, from the purchase of raw materials to the testing of raw materials, from the selection of raw material processing technology to the detection of the quality of parts, from the assembly of parts to the overall testing of the mold, and so on the manufacturing process related to the mold. Each step has a corresponding chart, and each link is as far as possible to ensure zero defects, and ultimately ensure the high quality of the mold delivery.
Design Inspection
Any JMJT or customer-provided product design, such as plastic molding process, SMC mold structure operation, the possibility of matching related parts, we will carry out a comprehensive analysis and inspection. All of these can effectively avoid mold repair work and costs caused by product design defects. We believe that an extra 10 minutes spent on product design can save a month in mold production. Through the accurate analysis of mold design, processing steps and mold structure application, we provide customers with a perfect solution. Mold testing involves many aspects, such as: mold strength, mold flow analysis, mold injection molding, cooling system, guidance system, specifications of various parts, customer machine selection and customer special mold requirements, etc., all these should be tested in accordance with mold design standards.
Purchase steel material testing
The procurement of spare parts has strict testing process and time control,the standardization of parts, the accuracy of size, the hardness of steel and material flow detection and so on.
Process quality control
Strict control of the size, each part after processing should be tested according to the mold design, and control tolerance, each part can only be processed after reaching the standard. Before CNC milling, all procedures should be strictly proofread. After completion, we will check the accuracy of each part with a coordinate measuring instrument. We have a lot of tests: training on professional machining techniques and machine maintenance; Self-inspection of machined workpieces and acceptance by quality department; Reasonable overtime work system and tooling control system.
Installation quality inspection
Complete inspection of SMC mold to ensure the continuity of mold structure and the standard of parts. The project manager and quality control personnel should inspect the mold according to the company's standards to ensure the quality of the product. When problems are found, they can be corrected immediately and errors can be effectively prevented.
In addition, we continuously carry out independent inspection of SMC mold cooling system, hydraulic oil duct system and hot runner system. The quality inspection department will submit the inspection report within 24 hours after the inspection of the mold. The report shall include product dimensions, appearance, injection parameters and physical parameters. We use different inspection standards and tools for different products. With the continuous upgrading of testing equipment, our product inspection has become more and more professional and reliable.
Mold Testing
To a certain extent, our testing of the mold is only to find out the problem of the mold rather than to solve the problem. Therefore, the test of the mold is divided into several steps, including empty running, high pressure pressure holding, high-speed injection and related long time mold running inspection.
Pre-shipment testing
According to the order documents, customer requirements and company standards, we will carry out strict acceptance testing of the mold. These order documents together with other inspection reports must be filed before the mold is shipped.
Project Processing Department
The technical personnel of the processing department should review the drawing before the mold processing to ensure that the mold can be shipped in the shortest reasonable time, which can not only shorten the production cycle but also solve the waste of raw materials.
Project Process Department
The staff of the process department must track the processing progress of the mold every day, take photos of each processing step of the mold, and then make a report in the form of mold progress report to the sales department.
Project process
The business department directly contacts the customer and discusses technical issues, and the independent responsibility system between the project manager and the salesman ensures that the project is executed accurately and clearly. Detailed and complete customer file management documents can also find omissions in time to solve problems. The project department is directly in charge of the progress department and the quality control Department to ensure the delivery time and quality of each mold. Follow up the process of each order, control the process to the specific moment, and seize the time to implement the task. Each technical meeting will ensure the good design scheme and processing technology of the mold. The process department controls every machining detail. The company has its own internal technical and cultural training, and every year the company invests a lot of research and development funds in the field of research and development. In order to improve the continuity of order management, regular training of sales department, project department, production department and quality inspection department. The aim is to improve the professional skills of the staff so that everyone can supervise the quality of the molds.
