Modern Era Molding Machines and Industrial Machines

Molding

Molding is the process of manufacturing shaping pliable raw material by using a rigid frame or model called a mold. The manufacturer who makes the mold is called moldmaker. Mold maker use different kinds of machine in molding process.

Types of Molding Machines

Blow Molding Machine

Blow molding is a manufacturing process by which hollow plastic parts are formed. There are main types of machine use for blow molding. Extrusion blow moulding machine adopts high quality components with both pneumatic and mechanical systems, and it is suitable for producing PE, PP and PC container products. Blow injection molding machine are widely used in medicine packing, the cosmetic packing, making up chemical industry, gifts & toys and so on. Stretch blow molding machine three steps in one from raw material to bottle finish product no more loss in damaged perform. Pet blow molding machine is used in bottling process of mineral water, soft drinks, edible oil and farm chemicals.

Mould machines manufacturer makes different kind of machine for molding process like candle moulding machine for make candles, pulp moulding machine for make egg trays, fruit trays and pallets. In-mold labeling machine is perfect equipment of many industries, such as lubricating oil bucket, dressing bottle, civil packing industry, etc.

Want to know about Injection Molding? Read it!

Basics of injection molding

Making polymers is a fantastic science. Then there is the matter of shaping the plastic into useful objects....another fantastic science. One of the most common methods of shaping plastic resins is a process called injection molding. Injection molding is accomplished by large machines called injection molding machinery.

What is injection molding?

Injection molding is a method of producing plastic parts. This is done with an injection molding machine. The shape of the part to be injection molded controlled by the geometry of the injection mold. The injection molding machine has two basic parts; the injection unit, which melts the plastic and then injects or moves it into the mold, and the clamping unit, which holds the injection mold. The unit clamps the mold in a closed position during injection, opens the mold after cooling, and ejects the finished part. Injection molding is a common method of producing intricate plastic components in high volume.

Plastic injection molding

Plastic injection molding is the primary process for manufacturing plastic parts. Plastic is known to be very versatile and economical material that is used in many applications. Although the tooling is expensive, the cost per part is very low. Complex geometries are possible and limited only to mold manufacture ability. Your computer, monitor, mouse and keyboard are injection molded plastics.

Injection molding involves taking plastic in the form of pellets or granules and heating this material unit a melt is obtained. Then the melt is forced into a split-die chamber/mold where is allowed to “cool” into the desired shape. The mold is then opened and the part is ejected, at which time the cycle is repeated.

Injection molding is performed by companies called molders. Some molders also design and build injection molds. The most common materials injection molded are plastic (plastic injection molding) and rubber (rubber injection molding).

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.
