This article discusses basic consideration for designing two-shot injection molds, which is referred to also as dual-shot, dual-injection, double-shot, double-injection, multi-shot, 2k molding, and overmolding Before tool design, one should check machine injection unit Injection unit sometimes constrain the tooling type. Material shrinkages for each material should be considered. Shrinkage may cause warpage and flash if those are not made up properly in tooling phase. If there is big different in melt temperature between materials, toolheat balancing should be .studied Tooling should consider gate location, access, allowable gate vestige. Draft angle in 2K molding is very critical factor which deciding wheremolded part stuck and rotating. In 1st shot molding, molded part should be stuck on rotating core and 2nd shot molding, molded part should remain on the side of ejecting system employed.   If part design imposing creating shut-off surface with molded part after rotating,Draft angle on shut-off surface should be…

Injection molding makes possible mass production of intricate, high performance, tight tolerance parts with very little secondary labor and minimal waste. It is defined as a process of shaping plastic by melting it and injecting it into a predesigned mold. As known, plastic injection molding has a bevy of advantages and benefits over comparative plastic processing and manufacturing methods. Here’s a look at the top 11 benefits of plastic injection molding.   1.High production rate There is a reason why plastic injection molding is one of the – if not the most common – technologies for long manufacturing runs: it’s fast. How fast? While the speed depends on the complexity of the mold itself, generally only about 15 to 30 seconds pass between cycle times. 2.Large Volume production The initial creation of a mold can be expensive, with the cost being a few thousand dollars.   But once the mold is built you can…

Overmolding injection process is used in many areas to create finished plastic parts and improve product efficiency. Without the process of,we would not have so many consumer  products that everyone wants and needs. Examples of overmolded products would be packing products,cell phones, toothbrush, computer monitors. So how exactly does the overmolding process work and what kind of defects we may see?     What is overmolding?     Overmolding is also called as  two-shot molding, results in parts in which it is clearly evident that more than one material is being used. It is a kind of injection molding process where only part of a product is molded in one material, and that molded piece is manipulated so the second material can be molded around, over, under, or through it to complete the final part. This method is sometimes referred to as in-mold assembly, since the resulting part effectively acts as an assembly of two materials…

What is injection molding process？ INSERT MOLDING is a type of injection molding. It is the process of molding thermoplastic material around an metal part to create a finished part that incorporates multiple materials.   The inserts for INSERT Moulds are typically metal stamping or thread parts.   The inserts are most commonly made of metal, typically brass, aluminum or stainless steel.  Threaded inserts are readily available in a number of standard sizes.  Bushings, sleeves and other simple metal forms are also used. Before injection molding, the inserts are placed on a fixed position in the mold and thermoplastics is injected into the mold to form the part. Most moldable thermoplastic resins are compatible with the insert molding process. This kind of products are usually used as structural parts in product development, and the strength requirements of the products are higher, so plastic material containing glass fiber (GF) is often chosen, and the content of GF in…
