Moulding and Extrusion

Blow moulding is a process used by companies that manufacture glass bottles and jars of various shapes and sizes. There are three types of blow moulding including injection blow moulding, injection stretch blow moulding and extrusion blow moulding.

Compression moulding is the process of putting moulding material into a preheated open mould and sealing with force to create soft elastic products. Some of the most common products that have derived from a compression moulding process include Wellington Boots, Silicone wristbands, and electrical insulators.

Gloves, balloons, and even condoms are produced by a process known as dip moulding. Materials used in dip moulding include latex, leneoprene, polyurethanes, silicones and epoxy. The benefit of dip moulding include cost (which is low) and a big negative is the time factor, since it’s a time intensive process.

Extrusion of metals is a manufacturing process used to make wires, metal bars, and tubes. Extrusion is used to manufacture objects with a fixed cross-sectional profile and it’s performed by pushing material through a die (which is a mould) of the desired cross-section shape.

Plastics extrusion is a manufacturing process which handles plastic pellets, granules, flakes and powders to create plastic products. Products produced by plastic extrusion include shopping bags, window frames, film, and wire insulation. They are created by taking plastic as a raw material and forcing through a continuous profile where it is met with heat and shaped, into many of the products we use every day.

Extrusion of rubber is used to make complex cross-section rubber products which are straight or coiled including 'D' section, Double 'D' section, 'U' channels, 'P' sections, Edging strips, Seal sections, Rubbing strips and Speed Restriction Strips for various industries including automotive and marine.

Injection moulding is a common manufacturing process used in mass production when a high volume is required of the same product. Common every day products produced by the injection moulding process include spools, packaging, bottle caps, automotive parts and components, Gameboys, and even the entire body panels of cars.

Rotational moulding is a slow method of moulding with a long cycle time. It’s because of this that the method is not always adopted in mass production, however, it is effective in making many hardwearing and durable goods. Some of which include storage tanks, furniture, road signs and bollards, planters, pet houses, toys, bins and refuse containers, doll parts, road cones, footballs, helmets, canoes, rowing boats, kayak hulls and playground slides.

Slush moulding, often called slush casting, is a metal moulding process that is used to produce hallow parts. The process is done by letting metal casting harden and set against a mould, where it solidifies to the mould wall from the inside of the casting. Slush moulding product is used to manufacture toys and parts that are ornamental in nature.

Vacuum forming lends itself well to the creation of almost any plastic shape. This is because, moulds can be created from almost any material (wood, concreate, foam or aluminum). Vacuuming forming (a method of thermoforming) is a process exercised all around the world, in the production of plastic materials such as bicycle helmets, canoes, and food packaging.
