What is an Injecting Machine?

[Lieberman]

An injecting machine usually refers to an injection molding machine, which is a type of manufacturing equipment used to produce plastic products.

Here’s a simple breakdown:

• 🔹 Purpose: It makes plastic parts by injecting molten plastic into a mold, where it cools and solidifies into the desired shape.
• 🔹 How it works:
  1. Feeding – Plastic pellets (or sometimes powder) are fed into the machine.
  2. Heating – The pellets are melted by heaters and a rotating screw.
  3. Injecting – The molten plastic is pushed into a metal mold under high pressure.
  4. Cooling – The mold is cooled, solidifying the part.
  5. Ejecting – The finished product is ejected from the mold.
• 🔹 Uses: Injection machines make everything from bottle caps, toys, and automotive parts to medical devices and electronic housings.

There are different types too:

• Hydraulic injection machines – powered by hydraulic systems.
• Electric injection machines – powered by electric motors (faster, more precise, energy-efficient).
• Hybrid machines – combine both technologies.

Quick analogy: Think of it like a waffle iron. You pour batter (plastic melt) into a mold (waffle shape), let it cool, and open it to get the product.
