With the long-term research experience of the R&D team in plastic molds, we have developed into a professional plastic molding technology and mold supplier, ranking among the top mold manufacturers in China and gaining unique advantages in the molding market.

With years of experience in plastic mold manufacturing, we are very strict with important issues and key points in plastic mold manufacturing. We have a rigorous mold manufacturing process and are renowned for hundreds of special mold structures, providing customers with advanced injection molding technology solutions.

Mould Design

Mold design requires determining the geometric shape, dimensions, tolerances, design criteria, technical requirements, plastic names used, shrinkage and color, as well as surface requirements of the product.

① Analyze the feasibility of designing mold products to ensure the correctness of their product drawings before design. On the other hand, we can familiarize ourselves with the importance of each component throughout the entire chassis to determine key dimensions.

② The work to be done after product analysis is to analyze what structure the product adopts and sort the products.

③ According to the product development plan, determine the dimensions of the templates in the drawings, including fixed plates, discharge plates, punches, inserts, etc. It is beneficial to prepare materials directly in the product development plan for drawing its diagram.

④ After the material preparation is completed, fully enter the drawing of the mold diagram, and create a new one in the material preparation diagram to draw various parts. When drawing the mold diagram, attention should be paid to every production point, such as fitter marks, cutting, lines, etc. Different processing techniques have complete layers, which is very beneficial for wire cutting and drawing management.

⑤ Proofread the mold drawings, set attachments, apply different layers to each different template, analyze the mold settings using the same benchmark, such as guide pillar holes, and set the product development drawings for each process in the settings diagram to ensure that the hole positions of each template are consistent, and whether the gap fit between the upper and lower parts of the bending position is correct.

New Model Conference

After the mold design is completed, the design review department reviews the design, including mold structure inspection, mold action and guidance system inspection, mold injection system inspection, mold cooling system inspection, mold ejection system inspection, and mold vulnerable parts inspection. All relevant personnel will participate in the new mold design technology meeting, proposing all technical points, such as the use of steel materials for mold components, the basic structure of the mold, plastic materials and their melt index, customer special requirements, injection molding machine parameters, and processing steps for components. After the design of the mold is confirmed by the customer, high-quality testing instruments are used to sample and test the steel material 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

Mold processing is the core link of mold manufacturing, which needs to be carried out according to the prescribed process to ensure the accuracy of the mold and product quality. The processing of molds is a complex process, and it is even more important to ensure the accuracy of this process during processing.

The mold processing process includes: mold blank preparation - rough machining of parts - semi precision machining - heat treatment - precision machining - cavity surface treatment - mold assembly - machine debugging.

① Most of the mold blanks are made of metal. Taking forging as an example, the raw materials used for forging are generally bars, plates, and pipes. Operators mainly choose based on the specific shape and geometric dimensions of the blanks. For thin plate blanks, ordinary or precision punching can be used. If forging circular parts is required, pipe cutting can also be used to make the blanks.

② For rough machining of parts, we take milling as an example. As long as the outer contour and island of the part are given, the machining trajectory can be generated, and arcs can be automatically added at the sharp corners of the trajectory to ensure smooth trajectory and meet the requirements of high-speed machining. It is mainly used for milling planes and grooves. Multiple contours and islands can be selected for processing.

③ The semi precision machining stage is to complete the machining of the secondary surface and prepare for the precision machining of the main surface.

④ Heat treatment is a comprehensive process of heating, insulation, and cooling materials in a certain medium, and controlling their performance by changing the surface or internal structure of the material. Heat treatment generally includes three processes: heating, insulation, and cooling, sometimes only two processes: heating and cooling. These processes are interconnected and uninterrupted.

⑤ Precision machining has a smaller machining allowance than rough machining. Choose the right cutting tool for cutting, control the speed and rotation of the tool, and pay attention to the size and appearance of the material.

⑥ Different surface treatment methods for molds can change the chemical composition, structure, and properties of the mold surface, improve and enhance the surface performance of the mold, such as hardness, wear resistance, friction performance, demolding performance, thermal insulation performance, high temperature resistance, and corrosion resistance. This step is of great significance for improving mold quality, significantly reducing production costs, improving production efficiency, and fully unleashing the potential of mold materials.

⑦ According to certain technical requirements, the process of assembling parts into components and combining them into components to form the entire machine. There are two forms of assembly: fixed assembly and mobile assembly. Different assembly methods are used for different batches of production.
