Vertical Injection Molding Process

Vertical Injection Molding Process What distinguishes a micro injection process from a “normal” Vertical Injection Molding process? Except for parts or structure sizes, the process is almost identical. Oen, even the same procedures are applied, both in the actual injection molding…

Milling

MILLING Milling is the use of several single-point cutting tools grouped around the periphery or face of the cutter or hob. The principles of single-point tool cutting apply to milling. In milling, the tool rotates and the movement of the…

thermoplastic and thermosetting

All plastic articles are initially derived from molding compounds. These molding compounds consist of a resin or binder and one or more of the following components: fillers, plasticizers, dyes and pigments, and lubricants. The “resin,” as the principal component, gives…

plastics

  The term “plastics” has been applied to those synthetic non-metallic materials that can be made sufficiently fluid to be shaped readily by casting, molding, or extruding, and which may be hardened subsequently to preserve the desired shape. Plastics as…

draft and hole design

Unless otherwise specified ,a slight draft is ordinarily given to the vertical surfaces of the piece. The reason for this is obvious when consideration is given to the fact that the injection molding plastic piece has to be released with the…

What Plastics Are

What Plastics Are Plastics are giant molecules, or high polymers. They consist of basic simple repeating chemical structural units called mers or monomers. When these monomers are joined together to form a long chain or giant molecule (by a polymerization…
