Injection mould hoses

Injection mould hoses are hoses that are used to transport coolant during the injection process. They are indispensable in the process of injecting molten material into the mould, which is then cooled and hardened. Injection mould hoses play a key role in maintaining the optimum temperature in the system, which is essential for the production of high quality products. They are therefore characterised by high heat and cold resistance and are available in different versions. The injection mould hose is most often made from EPDM rubber, but there are also plastic varieties (e.g. PVC or PTFE). However, regardless of the material version, they are characterised by their mechanical strength and insensitivity to most environmental conditions.

Injection mould hoses

How are injection mould hoses constructed?

In most cases, injection mould hoses have a construction that consists of three layers:

  • inner - made of a material resistant to coolant and high temperatures;
  • reinforcement - usually in the form of a synthetic braid, which provides resistance to high working pressure; 
  • outer - from a material resistant not only to high temperatures but also to mechanical damage and environmental conditions.

It is also worth noting that injection mould hoses are available in several colours. Of these, the black, red, and blue varieties are the most popular. This is no coincidence, as this makes it easy to distinguish between hoses for hot and cold coolant.

What are the advantages of injection mould hoses?

Injection mould hoses have several important advantages that affect the quality and efficiency of the entire process. These are:

  • effective temperature regulation - is key to maintaining consistently high product quality, in addition to speeding up the work cycle and increasing efficiency; 
  • flexibility and adaptability - as the hoses are available in many sizes and several material versions, you can adapt them to any moulding machine, in addition to ensuring greater precision and facilitating coolant flow even with a large bending radius;
  • durability - injection mould hoses are made from high-quality materials and are therefore resistant to rapid wear and tear and usually retain their properties for a long time (this translates into savings); 
  • heat control without increasing the overall process temperature - this is particularly important when working with very temperature-sensitive materials or when the thermal tolerance range is narrow

In summary, the above advantages directly affect the efficiency of moulding machines and increase the quality of the final products.

How to choose the right hose for an injection mould?

When you are choosing a hose for an injection mould, pay attention to the following points:

  • permissible working pressure - should correspond to the pressure of the medium in the system (poor choice of hose in this respect increases the risk of damage or even bursting of the hose);
  • operating temperature range - a very important parameter, as temperatures change rapidly in injection moulding. The injection moulding machine radiator hose should be able to withstand this (otherwise the material of the hose layers will degrade); 
  • nominal inner diameter - match this to the size of the installation and the working pressure; 
  • durability and flexibility - check how resistant the hose is to wear and tear, and whether it has sufficient flexibility to work in the sometimes tight curves of injection moulding installations; 
  • environmental conditions - if the hoses will come into contact with chemicals or other hazards during operation, select the manufacturing material to withstand the circumstances.

Bear the above points in mind before making a final purchasing decision, and you will be purchasing a hose that will work well for your installation and provide consistent, high performance over the long term.

FAQ

How do injection mould hoses differ from standard hoses?

arrow-up

Injection mould hoses differ from standard hoses in that they are designed for high temperatures and pressures and are resistant to substances in the coolant.

What is the service life of injection mould hoses?

arrow-up

The service life of injection mould hoses depends on a number of issues, such as the way they are used, the working conditions and the care they take. However, under optimal conditions, they should retain their properties for at least several years.

How are injection mould hoses assembled?

arrow-up

Injection mould hoses are installed using special connectors/quick release couplings and clamps or sleeves, which ensure strong clamping and high tightness. When installing, it is best to follow the manufacturer's recommendations, so you can be sure of a well-made connection.

Can a damaged injection mould hose be repaired?

arrow-up

In some cases, a damaged injection mould hose can be repaired and continued to be used. However, it is usually much more economical to replace the hose with a new one. By doing so, you will avoid excessive downtime in your operation, as well as potential drops in productivity or the risk of a dangerous failure.
