Everything You Need To Know About Plastic Moulding Machine

Plastic moulding machines are available in a range of sizes from small table top models to large sized machines. Micromoulding machines are used in making microscopic medical parts with amazing precision. The productivity of plastic moulding machines might also vary from case to case. High productivity machines can produce over 200million parts in one year. There are fully automatic machines that can work on their own with high precision and efficacy.

Different Types of Moulding Machines
There are various types of moulding machines, which are categorized as per the functions.

•  Rotomoulding Machine (Rotational molding) is used to make many types of hollow items like plastic. Rot molding was first invented in the 1940s and over the years it has evolved to be a popular method. Technological advancements and developments in plastic powders have resulted in a considerable surge in its usage.

•  A pulverizer is yet another mechanical machine which is used to grind plastic metals, resin, tire, coal or glass into granules or fine powder. Pulverizer is used in plastic industry for PVC Recycling, Rotational Molding, Compounding and Master batching. The high demand for plastic and rubber in powder form has resulted in the development of modern pulverizing systems.

Features of Pulverizers
Pulverizers are heavy duty machines with a production capacity that ranges from 30-400 Kgs and can be operated by a single person. Low maintenance and higher production capacity makes it an economical option. In addition to single mill pulverizer machines there are also Twin Mill Pulveriser Machine, which are well known for their high capacity and steady performance.

Plastic Moulds are normally made of steel or aluminum. Though Steel moulds are costly, these last longer whereas aluminum moulds are cheaper and when designed with computerized equipments, it is found to be useful for moulding hundreds of products. The quality of the moulded part is greatly influenced by the quality of the mould. The molten resin should be at the right temperature and pressure to ensure uniformity.  The edges of the mould must have precise closing so that leakages of the molten matter can be avoided.
