Plastic Injection Molding Machines 

Injection Moulding of plastic machines are undisputedly some of the most useful equipment focused mainly on producing anything involving plastics. Plastic injection molding machines can manufacture anything from small parts like hearing aids tohuge components like truck hoods.

Types of plastic injection molding machines

1. Horizontal Injection Molding Machine

Melted plastic is injected into a clamp to operate horizontal plastic injection holders. A mould created in the form of the item you want to make is held in place by the clamp. The greatest option for producing both simple and intricate plastic parts is to use these machines. With horizontal injection moulding machines, there are several different machine types to choose from, including electric, hydraulic, toggle, hybrid, double shot, and multi-shot.

2. Vertical Injection Molding Machine

A product can be produced using a vertical injection moulding machine with an insert injected, and the plastic will shape and form around the insert. Electrical parts and screwdrivers are a couple of examples. On vertical injection moulders, a shuttle or rotary table is typically attached to aid in conveying the mould.

You can find your preferred plastic injection machine depending on the requirements of the type of product you’re looking to produce. Whether you’re looking for a five-ton or 4,500-ton injection molder, you need to look in the right market and get the best equipment that meets your requirements and budget.

The Injection Molding Process

Injection molding is the most common manufacturing process for producing plastic components. Although it was invented a long time ago, it remains one of the best and most productive ways of manufacturing highly complex parts while saving production costs. 

Most of the products we use today (regardless of their application, complexity, and size) are manufactured through injection molding. The injection molding process is mainly used to produce a wide variety of thin-walled plastic parts, including other open containers like buckets, plastic housing (a thin-walled enclosure with several ribs on the interior) often used in several household appliances, consumer electronics, automotive dashboards, power tools, household appliances, etc.

Injection mold is also used to produce items we see every day, such as toothbrushes, valves, syringes, small plastic toys, etc.

The thermoplastics commonly used in injection molding include:

  • Nylon PA
  • Acrylonitrile-Butadiene-Styrene (ABS)
  • Polypropylene
  • Polycarbonate

Components of a Plastic Injection Molding Machine

Below are some of the components or parts of the injection molding machine, they include:

  • Material hopper (this s the funnel into the barrel)
  • Feed zone
  • Screw-type plunger
  • Nozzle
  • Injection chamber
  • Stationary platen (often made of steel and holds part of the mold)
  • Barrel
  • Rotating screw
  • Heating unit
  • Movable platen (often made of steel and holds part of the mold)
  • Injection ram
  • Clamping cylinder

All these components or parts work together to keep the mold in place so that the final shape of the plastic can be formed without any errors or defects.


The plastic injection molding machine is still the best option for making and designing high-quality and unique parts without any glitches. The injection molding process allows manufacturers to create intricate and complex shapes and details while saving production costs.
