Injection Moulding Plastic Egg Tray Mould

In order  to  get right injection mould,Here a few tips for your reference.

1.Choosing  material

It will help your mould maker if you konw what polymer you are using  before starting the mould. When you choosing  material for your injection moulded part,figure out what you needs,you can discuss with material representative,i think these guys will help you select a material that best meets your parts.If you decide on one  material,then don’t change your mind.Remember, it does not have to be the most expensive resin to be a quality material.

2.Selecting the right mould maker

There are many kinds of mould makers in China,some are very large,some are small.Just keeping in mind the requirements for your parts,select a mould maker that is capable.If your requirements are low,stay away from the big injection mould maker,their mould cost is very high.

3.Get the specification and design right in the beginning

Make sure you specify everything you want up front.Getting  the design optimised for injection moulding is probably the single most important thing.Describe intimately the function of the part and which parts need to fit together and how well they need to do that——if you are getting a drawing done,this will be set up as tolerances.The mould maker should have these to work to for mould structure drawing.If the mould maker have the spec up front,they should make a product that makes that part to how you want it.If you haven’t specced it before,sometimes this can be a painful process as you may end up with bill to pay making minor modification when the part hasn’t moulded correctly.

4. Choose appropriate steel

If you choose wrong steel,the part may get stuck in the mould,can't eject properly.

If you are expecting 1000 part/year for 5 years then finish,a softer steel(like aluminium) will be recommended.

If you want running for over 15 years,and there’s no reason that if you choose a good grade of stool.Remember,the longer the mould runs,the more profitable it is.

What material you use will affect steel choice:for example,if you want to make parts in PVC,then we’d recommend a stainless steel mould due to it’s corrosive nature.
