Injection molding is one of the most popular methods used to produce plastic products. This is because it’s fast, efficient, and cost effective. However, if you want to get the most out of your machine, then you should know how to properly service and maintain it.

This article will give you some tips on how to service an injection molding machine so that it can last for a long time.

Maintenance means performing regular checks on your machine so that you can identify any problems before they become major ones. There are many different types of maintenance tasks that should be performed on an injection molding machine including cleaning out dust from around the machine, lubricating moving parts, changing filters (if necessary), replacing worn out parts such as belts or hoses, etc…

Key Parts to Check During Maintenance

The best way to maintain an injection molding machine is by regularly inspecting it and making sure all parts are in good working order. Many times, there can be problems that go unnoticed until they become serious enough to cause damage to the machine or its components.

Check the seals and gaskets

Injection molding machines use rubber seals and gaskets to ensure that no material leaks into other areas of the machine. If these seals begin to deteriorate or crack over time, then you can expect problems with your process as well as expensive repairs for your equipment.

Check for leaks

Leaks can occur anywhere on the machine, but especially near the valves where material flows through them from one part of the molding process to another. These leaks can cause damage to other areas of your equipment as well as negatively impact your production rates due to wasted resources such as materials or energy usage.

Injection unit

This is one of the main components of an injection molding machine. It consists of a plunger and a barrel where molten plastic is stored. The plunger pushes the material out of its chamber when it reaches a certain temperature and pressure level.

Cooling device

This component helps in cooling down hot materials so that they become solidified into their final shape after being injected into two halves of a mold cavity by an injection unit.


Injection molding machines are complex, highly-mechanized systems that can be difficult to service. Here are some of the parts you should avoid touching when servicing an injection molding machine: Feeders; Tray Lifter assemblies; Center Core assembly; Mold clamp system and the clamp locks.

Injection molding machines are made from metal, which can be very hot after use. You can burn yourself if you touch these parts. Similarly these machines have moving parts like screws, pistons and nozzles that could injure you if you come in contact with them while they are still moving. You should also be aware of electrical components operating under high voltage and can cause electric shocks if touched improperly by human hands.
