What is Mould & Types of Mould

Moulding is a manufacturing technique for making parts from plastic material.

• Molten plastic is injected at high pressure into a mold, which is the inverse of the desired shape.
• The mould is made by a mold maker from metal usually either steel, aluminum and precision-machined to form the features of the desired part.
• Injection moulding is very widely used for manufacturing a variety of parts from the smallest component to entire body panels of cars.

Types of Moulds

1) Compression Mould

Compression Moulding is one of three processes used to mold parts. Compression molding is the oldest and simplest way to make products. In some specific applications, compression molding is still the best way.

2) Transfer Mould

Transfer Molding involves having a "piston and cylinder" like device built into the mold so that the rubber may be squirted into the cavity through small holes.

3) Extrusion Mould

Extrusion moulding is a method used to form thermoplastic materials into continuous sheet film, tubes, rods and other shapes and to coat wiring and cable. The process produces continuous two dimensional shapes like sheet, pipe, film, tubing etc. The material is fed into the extruder where it is melted and pumped out of the extrusion die.

4) Injection Mould

Injection Molding is the most advanced typical method of molding plastic products. Injection molding produces the most consistent results by automating all aspects of how the material gets into the mold. In injection molding, the material is worked and warmed and then squirted into the mold at controlled speeds, pressures and temperatures.

5) Hot Runner Mould

Hot runner molds are two plate molds with a heated runner system inside one half of the mold. A hot runner system is divided into two parts: the manifold and the drops. The manifold has channels that convey the plastic on a single plane, parallel to the parting line, to a point above the cavity. The drops situated perpendicular to the manifold, convey the plastic from the manifold to the part.

6) Blow Mould

Blowing molding is the primary method to form hollow plastic objects such as soda bottles. Blow molding is another common type of plastic molding. In this process a plastic tubular form, produced by extrusion or injection molding, is used to form the part. This form called a parson is softened inside a mold and then injected with air or other compressed gas.

This expands the parson against the sides of the mold cavity, forming a hollow object the size and shape of the mold.

Moulding Industry – Discover Everything You Should Know About Moulds and its Types

Moulding industry is getting bigger rapidly and the demand for moulding and trim will reach $9.8 Billion only in the US next year, chiefly due to the expansion in nonresidential construction. The fastest growth is expected in exterior moulding and trim, which will be followed very closely by metal stairwork. When it comes to material, plastic molding and trim products will offer the best prospects.

Moulding industry is a huge industry. So, let’s now talk about different types of moulds like plastic moulding, used injection moulds, injection moulding machines, extrusion moulding, rotational moulding, automotive moulding and OEM moulding.

Plastic Mould:

Blow moulding machine will be the main part of your business if you are involved in creating plastic products. Blow molding machine will turn plastic into a mold to make light & strong products.

Injection Moulding:

Injection moulding a way of manufacturing and, hence, helps make parts from thermoplastic and thermosetting plastic materials. Molten plastic is converted into a mould, which is the opposite of the product’s structure.

Injection Moulding Machines:

Injection moulding machines are also known as presses. These machines hold the moulds in which the components are created.

Extrusion Moulding:

Extrusion moulding is a process of creating hoses, drinking straws, pipes, curtain tracks, rods and fibers. Long tube-like shapes are formed through extrusion moulding.

Rotational Moulding:

Rotational moulding is a cost-effective method for producing hollow plastic products. Through this method very little waste is produced and costs are low as compared to blow moulding and injection moulding.

Automotive Moulding:

Automotive moulding is used on the body of the car for decoration and protection reasons. For example, door moulding, footrest moulding, etc. Both the detail and the material come under the term automotive moulding.

OEM Moulding:

OEM stands for Original Equipment Manufacturer. You can provide your own specifications when you want to get a particular product.

It is imperative to decide what sort of moulding you require. Understand all different types and then choose the one that best suits your needs.
