Based on Jingsheng(Kingsjeng)’s over a decade of injection molding production experience, the efficient production of insert plastic products indeed requires collaboration across multiple links, with the core lying in four key factors: insert treatment, process control, equipment adaptation, and quality closed-loop management.

In the volatile business world, some companies fade away like shooting stars, while others survive cycles and achieve long-term success. The root cause lies in the boss's vision, which is often the key factor determining a company's development and fate.

T0 Tooling Trial (Tooling Trial 0, i.e., First Trial Run) is the most critical verification step in the injection mold development process. Its core objective is to comprehensively test mold design, manufacturing accuracy, and product feasibility through the first actual injection molding, clearing key obstacles for subsequent optimization and mass production, and avoiding major risks after mass production begins.  

Based on over a decade of experience in cooperating with domestic and international customers and manufacturing various plastic products, Kingsjeng Technology believes that the quality inspection of plastic products needs to cover core dimensions such as safety, functionality, stability, and appearance compliance. 

In response to the needs of small-batch, multi-model injection molding, mold design must strike a precise balance between quality and cost. Here are systematic suggestions from Kingsjeng, integrating industry technologies and practical cases:

In the production chain of plastic products, the injection mold is known as the "Mother of Products". This title stems from its core position in the birth process of products - it not only determines the shape and performance of products, but also runs through the entire life cycle from design to mass production, serving as a "bridge" connecting creative ideas and physical products. Specifically, this "maternal" core role is reflected in the following three dimensions:

Through over 10 years of production experience, Kingsjeng has identified key measures. The core of producing qualified transparent plastic parts (such as PMMA, PC, PS, etc.) lies in achieving the three core goals of "no appearance defects", "qualified light transmittance", and "no internal stress or low stress". Strict control is required in multiple links including raw materials, molds, processes, equipment, and environment. The key points are as follows:
