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.
