You could design bolt slots in the mould halves to clamp them directly. \nInitially our moulds had through-bolts which was of course silly and we quickly moved to a significant 10mm steel plate either side of the mould clamped together with M10 bolts. This setup becomes really slick as you can slide the moulds out of the clamp easily, separate the part and slot it back together when complete. " - text: "We use LDPE sourced from wheel nut indicators (Checkpoints) which is vibrantly coloured and very nice quality to work with. It injects nicely between 160-170*C. \nFor each tool we put 40g of plastic into the injection moulder - accounting for some leakage at the beginning to ensure the plastic is flowing nicely and over-spill at the end to ensure the mould is 100% filled. \nWe inject the plastic relatively slowly by hand and hold the pressure once the mould is filled (indicated by when it overflows at the top). Using nylon moulds means that the injected plastic is insulated so it doesn't cool quickly so wants to escape if you don't hold the pressure after injecting.

If you take out the part too early, it may be soft and you risk deforming it. \nEqually, don't leave it in longer than 6 minutes as the shrinkage may cause it to hug the sides which makes it much harder to release! \n\nUnclamp the mould, peel the part from the mould and leave the moulds to cool (being a plastic mould, it keeps warm for longer which can cause issues over multiple injections). A fan can help this process. \n\nUsing multiple moulds and clamps here enables you to get quick cycle times - you can be injecting the next tools whilst the previous ones cool for example.
