An injection moulding machine is a complex piece of machinery that creates one solid part by injecting molten materials through a reciprocating screw system into a mould. This machine is made of many components; it is primarily consisted of a hopper, a barrel containing a reciprocating screw, temperature control devices, a clamping unit and the […]

In this article, we’re talking about gates. And no, not the kind that you shut behind you when you’re leaving the farm. In plastic injection moulding a Gate is where the molten plastic enters the cavity of the tool. That’s to say it’s different from the sprue or runner. Sprues and runners are simply there […]

An injection mould is the key to creating a successful one-piece finished plastic or metal component. Melted material is forced from the injection moulding machine into the mould (which is usually cool) where it sets. The result is a solid piece of the material which may be a component to, or the whole of, a […]

Plastics are the common name for man made polymers. Chemically, these materials are made up of a single unit, the monomer, which will link up with millions of itself to form long chains. The length of these chains, if they have many branches, and how tightly they wrap together determine the physical properties of the […]

Warpage: it’s the bane of the designer when it comes to injection moulding. Warpage occurs when cooling of the part is inconsistent. A section of the part will set whilst another remains molten. The set area will restrict the proper setting of the still molten area, resulting in warped parts that must be rejected or […]
