When a casting product has solidified and has been taken out of the mould, that does not mean that the product is ready to be sent to the customer straight away. In principle, every product should be deburred and grouting and de-aeration must be removed. To arrive at an actual end product, a number of finishing and/or surface finishing activities must be carried out so that the aluminium casting can justifiably be called an end product.
Perla AluCast almost always manufactures larger series, so we have in-house CNC machinery in our factories to cope with the high numbers. CNC (Computer Numerical Control) finishing has a number of major advantages over conventional manual finishing. The main advantages are the accuracy and repeatability of the finishing with CNC, which means there are hardly any rejects and quality is guaranteed. Examples of finishing include drilling, tapping, grinding, milling, boring and honing.
All finishing work, both manual finishing for minor simple adjustments and the CNC finishing, is immediately performed by our people in our factories. This means that the chain is very short, which once again saves you time and money. What’s more, it increases the reliability and quality of the product.
Surface treatment can increase the hardness and life span of your product; it also serves as decoration and more effectively protects your product against corrosion. Powder coating, for example, is an electro-static painting process in which compressed air is used to spray negatively charged powder onto a positively charged product. This ensures that the powder temporarily sticks to the product, after which it is melted in the oven. With anodisation, electrolytic treatment is used to apply an oxide layer to the aluminium casting.
Perla AluCast can offer you both techniques, which we outsource to parties in our network. We have been working successfully with some of these third parties for more than 20 years. Immediately after production, we can outsource this work locally or, depending on the complexity of the treatment, in the Netherlands. Here, too, the people of Perla AluCast have the necessary experience to help you make the right choices.
Other casting products must often be integrated into the aluminium casting, or non-casting components such as plastic or steel must be added/mounted. The integration of fixing materials can also be an important part of the process. We can arrange for these assembly steps to be carried out for you locally in our foundries or we can outsource them in our network, which we have carefully built up over the years. In some cases, we also manufacture assembly tools in-house so that the assembly can take place quickly, repeatedly and economically.
