This question was asked by many customers who normally have 3~5 mould suppliers in China.
For example, a customer requires the mould cycle time to be 30s. However, when the mould exported to the client, the cycle time is 60s, no matter how they modify the process it’s useless. Does your company have the same experience?

There are many reasons will effect the cycle time, today I’d like to share the most important reasons and solutions.

1.When we receive customers requirement of the mould, we will carefully check it, the mould life, surface requirement, raw material, cycle time and so on.
2.Then will make professional mouldflow analysis to the parts which we are not familiar, it can reflect the injection point, fill time,Packing/Holding time ,Cooling time , the injection pressure, clamp force, shot size and so on, even tonnage force required to hold the shut during the moulding process.
3.According to the mould flow analysis result, we will pay more attention to the gate location, cooling line, it determines the injection cycle time.
4.Use proper tonnage injection machine to trail the mould, this is very very important.

Our factory is equipped with advanced injection machines replacing the old machines because they were different from European standard machines. Sometimes we had to use a too large machine to try a small mould only because the mould thickness is beyond, it caused the parameter completely wrong. Our new machines’ function are more similar to European Standard and by using proper tonnage machines to the mould trial will guarantee the cycle time. So making sure to do the right thing ay each step is crucial.
