The quality of molds is believed to be one of the topics that our friends in the mold industry are most concerned about, because the quality of molds will directly affect the quality and iteration cycle of our mold products.

If the mold quality is not up to standard, it will not only cause mold loss and replacement cost, but also cause economic cost caused by low efficiency and poor products. So, how to judge the quality of the mold? Let's look at it with a red plum shape ~ ~

Identify the quality of the mold mainly through these aspects.

First, the quality of mold products; The quality of the mold itself can be reflected by the dimensional stability and consistency of the products manufactured by the mold, the surface smoothness of the products and the material utilization rate of the products.

Second, the service life; On the premise of ensuring product quality, the number of working cycles that the mold can complete or the number of parts produced.

Third, the use and maintenance of molds; Whether it is the most convenient to use, easy to demould, and whether the auxiliary production time is as short as possible. Maintenance cost, maintenance cycle, the length of mold maintenance cycle and maintenance cost are also included in the evaluation scope of mold quality.

Taizhou Hongmei Molding, whether it is Hongmei mold manufacturing or product design provided by customers, we will conduct all-round analysis and inspection, such as the feasibility of plastic molding process, the feasibility of plastic mold structure and movement, and the matching of all related plastic parts. It can avoid unnecessary plastic mold maintenance work such as trimming and scrapping caused by product design errors when using plastic molds. We believe that we spent more than 10 minutes on the design, which may reduce the production time by one month.

Of course, the quality of a pair of molds is also inseparable from mold design and inspection;

A, plastic mold design check:

Through accurate analysis, predictable rationality analysis of plastic mold design, optimized process analysis and structural application of plastic mold, the most professional solution can be provided. 1 noon 8 Wandering Liu Baling Dance's wife; And provide the most suitable plastic mold performance and technical specifications according to customer requirements. ?

At the same time, the inspection covers the strength of plastic mold, mold flow analysis, plastic mold ejection, rationality of cooling system and guiding system, application of plastic mold parts specifications, selection of customer machines and application of special requirements. It must be tested according to the design standard of Hongmei mold plastic mold. ?

Second, the steel procurement inspection:

The procurement of spare parts has strict inspection procedures and time control, standardization of parts, dimensional accuracy, hardness of plastic mold materials and detection of material defects.

3. Accurately control the dimensions, and carry out self-inspection on each die part according to the requirements of drawing dimensions and tolerance limit control. Only after passing the inspection can the spare parts enter the next working step. The previous wrong workpiece is not allowed to flow into the next processing step. For CNC milling, the program needs to be strictly audited before machining. After machining, we will check and control the accuracy through three-dimensional coordinate measurement. We have many measures: professional mold technical training and machine maintenance; Self-inspection of mould parts and acceptance by quality department; Reasonable shift system and tooling control system.

Four: plastic mold installation quality inspection:

Conduct a comprehensive inspection of plastic molds to ensure structural consistency and standardization of spare parts. Project managers and quality control personnel should participate in the inspection of plastic molds according to company standards to ensure product quality. If mistakes are found, they can be corrected in time. It can also prevent mistakes. In addition, we will also carry out independent standardized tests on the cooling system, hydraulic oil circuit system and hot runner system of plastic molds. ?

Verb (abbreviation of verb) Acceptance of sample size and plastic mold size:?

The quality control department shall conduct product inspection and submit the test report within 24 hours after the plastic mold test. The report should include all-round testing and analysis of product size, appearance, injection molding process and physical parameters. We use different inspection standards and tools for different products. Our laboratory has carried out different tests such as high-pressure injection, high-speed injection and long-term automatic operation test. The quality control department puts forward suggestions for modification and improvement of nonconforming products. We have accumulated rich experience in red plum molding, which is suitable for plastic mold production and provides good solutions for more and more customers. With the continuous improvement of equipment and measuring and testing instruments, our product inspection tends to be professional. ?

The above is the view of Hongmei Mould on "How to judge the quality of a good mould". I hope it helps you.
