Pre-project Evaluation
Material Selection
Materials are the core elements of molds, affecting the quality, service life, machining accuracy, and production costs of molds.
Precise Material Selection
Based on the product's usage environment and performance requirements (such as mechanical strength, high-temperature resistance, chemical corrosion resistance, etc.), carefully select suitable engineering plastics from the field of polymer materials.
For example, for automotive interior parts that need to withstand significant external forces, high-strength polycarbonate (PC) is selected. If the product needs to be used in high-temperature environments for a long time, such as electrical appliance casings, polyphenylene sulfide (PPS) with excellent heat resistance will be adopted to ensure that the material properties are highly consistent with the product requirements.
Scientific Optimization
With the help of professional material performance analysis software, accurately simulate the flow, cooling, shrinkage, and other behaviors of engineering plastics during the injection molding process. By analyzing the simulation data, optimize the material formulation or model selection.
For instance, adjusting the proportion of additives to improve the fluidity of plastics, or changing to a material model more suitable for the mold structure, thus effectively reducing production costs while enhancing product molding accuracy and overall quality.

Design Scheme Evaluation
During the design process of plastic products, we highly value the close connection between product design and mold design. We conduct analysis and evaluation on the feasibility in actual production from aspects such as mold structure, injection molding process, product function realization, and production experience. In this way, we can effectively reduce mold modifications and material waste caused by improper design, and avoid overly complex designs that increase production difficulty. By fully considering production factors at the design stage, we ensure the feasibility of the design scheme, thereby reducing production costs.
Mold Design, Development and Manufacturing
During mold design, we use CAD/CAM/CAE software to construct a 3D model of the mold. We design various parts of the mold, such as the cavity, core, gating system and cooling system, to ensure accurate mold dimensions and perfect assembly of all components. When manufacturing the mold, advanced processing technologies such as high-speed milling, electrical discharge machining, and wire electrical discharge machining are adopted, together with high-precision processing equipment. This can ensure the manufacturing quality of the mold, strictly control processing errors, and make the mold more durable.
Optimizing the Production Process to Enhance Manufacturing Speed and Quality
Through repeated experiments or simulations, we identify the most suitable injection speed, packing pressure, and cooling time. This can significantly reduce product molding time and improve production efficiency.
With our extensive experience in injection molding processes, we can provide practical advice.
For example, during the product design stage, we can help simplify the structure to accelerate production; or optimize the mold design to ensure smoother part demolding. By addressing production challenges at the source, we comprehensively enhance production efficiency.
Mass Production and Quality Control
After the debugging is completed, the mass production stage is entered. During the production process, strict quality control is carried out. The product quality is monitored through sampling inspection, full inspection and other methods to ensure that each product meets the standards.
