A hot runner mould is a type of injection molding assembly that combines two plates. The mould uses a valve gate system to inject the plastics. The cost of this mould is more than the cold runner mould, so you may want to look for a semi-hot runner mold. Here are some of the benefits of this mold. ... read more
The process of manufacturing PET preform injections is characterized by the electrochemical reaction between two metals. This reaction produces a thin coating of another metal, which makes the surface of the mould smooth and provides better finishing. After the injection process, a manufactured PET... read more

Unscrewing threads When creating a plastic flip top cap, you have a couple of options when it comes to unthreading the closure threads. First, you can opt for an unscrewing thread, which is more challenging but will not break the integrity of the thread. Second, you can opt for a jump thread, which ... read more
When designing a CAP MOULD, consider how the cap will be unscrewed. The method of unscrewing depends on features of the cap that are not inherent to the product. The unscrewing method must be indicated on the cap drawing. The cap is unscrewed by either a stripper ring, which holds the cap off the co... read more
