External-threaded injection molded parts are essential in many industries, offering reliable connections and functional performance. This case study explains how precise mold design—using threaded rings, side core pulling, or inclined ejector pins—ensures flawless demolding and thread accuracy. Discover how SG Proto maintains tight quality control for every detail in the injection molding process.

Copper electrodes play a vital role in EDM mold cavity machining, offering exceptional precision and conductivity. From material selection to spark erosion machining, they ensure accurate and efficient mold fabrication—making them essential for producing high-quality molds.

SG PROTO utilized two-shot injection molding to create a high-precision shell for a European home appliance manufacturer. By combining PC and ABS materials, we achieved excellent transparency, impact strength, and color contrast. Through optimized mold design and process parameters, we ensured dimensional accuracy and perfect material adhesion. Compared to traditional overmolding, two-shot molding reduces production steps and cost while enhancing the product's premium look.

Discover how SG PROTO builds high-precision injection molds with advanced engineering, quality materials, and strict testing. From design to validation, we ensure every mold delivers accuracy, durability, and efficiency for mass production.
