When we design a mold, if angular slider is too long, we need use locking block to make angular slider pin is shorter and stronger. If we don’t make locking block , angular slider pin can be broken during working time. advantage of block: easy installation and maintenance, although the angular pin mold was broken […]
Sprue bushing injection molding is connecting between nozzle of injection machine and injection molding. It is same a part of the runner, which allows the molten plastic material to be injected into the mold through the nozzle of an injection machine. I. Construction of sprue bushing injection molding. + Sprue bush can design follow your […]
Locating ring injection mold is simple part but, very important when mold base attach to injection machine. It use to locate or align sprue of mold and nozzle of injection machine. It is usually in center of mold. Sometimes, it is offset to reduce mold side. I. Locating ring injection design. 1. Dimension. + Locating […]
In this post I will explain construction injection mold classification. Injection mold classification depend on structure plastic parts. If a sample has compound shape, the mold is more difficult than simple shape, and we design mold we need to take care injection machine, number of cavities, plastic material,… of customer.
In this post I will explain injection molding runner components of mold part. There are 4 main items of runner components: runner lock pin, runner lock pin lock, runner lock pin bushing, ejector runner. It is different functions between the two mold plate and three plate mold, but there are several components that can be […]
Design sprue gate or direct gate is the simplest and oldest kind of gate. it connects directly end sprue to the molding. It has a circular cross-section, is slightly tapered, and merges with its largest cross-section in to the part. The sprue gate always is at the thickest section of the product. It uses for […]
