Scientific instrument mold development

Time:2024-09-29

Development of scientific instrument molds - Establishing long-term cooperative relationships to achieve win-win outcomes. The cooperative company is a listed company dedicated to scientific analysis instruments. Most of the plastics used have anti-corrosion and high temperature resistance requirements, and special plastics have a wide range of applications. The customer's products have shifted from machining to injection molding, and their product characteristics require certain difficulties in forming effects, especially PFA and FEP materials. The shrinkage rate of products with different wall thicknesses ranges from 3% to 6%, and the mold temperature also has a significant impact on the product. The size is very difficult to control, and the injection molding temperature of the product reaches around 340 degrees Celsius, and the mold temperature reaches 220 degrees Celsius. The requirements for the hot runner are also relatively high. In addition, product injection molding is very sensitive to internal stress. As long as there is internal stress during the injection molding process, the product will turn black and not transparent.

Our company must consider comprehensive aspects such as mold design stage prediction and technical breakthroughs in molding to develop a process plan that belongs to this customer. After several years of adaptation, our professionalism and service have gained great recognition from customers, and both parties have become long-term partners.
