Plastic Parts Company - Carlow, Ireland

Plastic Parts company is a leader among mould makers. Our main focus is creating the highest quality products. Plastic Parts Company is an ireland injection mould company. Our company concentrates on mould design and mould manufacture. The main products are Plastic Injection Mould, Injection Moulding and Custom Moulds.

I spent a few years as an IMD specialist for a Tekra and Bayer films. The most helpful advice I can offer is to get all parties involved at the very beginning of the design phase- tooling, moulding, mould supplier, mould printer, mould former/trimmed (if not being done in house). Both the part and all the related tooling need to be designed as a team for a good chance of success- retrofitting for IMD after the fact is almost always a recipe for failure. If at all

possible, make sure all partners in the project have IMD/IML background.

We are developing a range of chairs with plastic shells (used with a variety of bases) for an international furniture brand. I am interested to hear from reps and engineers with suggestions of innovative advanced polymers. This will be a high quality modern range that will sell into top commercial fit-outs.

For this task, the system will need a low molecular weight (LMW) HALS. If you have 20 - 40 % of mineral fillers, the actually you will not really need to have an organic UV absorber present as the fillers will screen of the harmful UV radiation. In addition to the LMW HALS though, you should consider an addition of a HMW HALS (as this besides the radical scavening effect for UV protection also provides LTHS (long term heat stability)), which LMW HALS cannot do.

As always, any starting pojnt for UV stabilization starts with a proper AO package, which need to comprise both primary- and secondary antioxidants.

Choosing the filler is crusial as trace metals will reduce the UV stability. Coated grades of CaCO3 are less critical while unpure talcum will be the worst. The downside of the CaCO3 is that it will not provide the same level of stiffness as talcum in a like for like amount in final (due to the cubic morphology of CACO3 vs the platelet morphology of talcum). A mix of these fillers may provide a good balance.
