Dela Plast is a plastic injection moulding manufacturer in Pretoria. We specialise in contract injection moulding which means we supply customers products of which the customer owns the mould. We get many pricing requests from enthusiastic customers for plastic products or components they require for their businesses. Purchasing a non-existing plastic component is not as easy as just placing an order. A lot of work goes into the product design that is not always foreseen when a great idea is conceived. But through proper design and planning, mould and production costs can be reduced.

Product development is a process from design to production. We can advise you on your product development process:

One of the main problems is that a client does not always know how to go about in developing this product and what the costs related are. One of the biggest hurdles in plastic injection moulding is the costs of the moulds. Moulds need to be made of high quality tool steel to resist the impact of the pressure of the heated plastic that goes through the tiny components(gates) to fill your mould for uniform products.
But before we get ahead of ourselves lets look at the steps for plastic product development:

10 Steps for manufacturing a new Plastic Injection Moulded product:

1. Acquire a great idea

This idea for a plastic product should be feasible and should be able to sell thousands and thousands of plastic parts! It is very important to have a high production rate to make the idea feasible!

2. Complete the design

Design the product keeping in mind important factors like material choice, uniform wall thickness, avoiding sharp corners if possible etc. Planning is very important to prevent costly mistakes by thinking the design through. Ideally do a 3D design.

3. Find a local plastic injection moulder

Find a reputable plastic injection moulding company and have a brainstorming session regarding your idea. Discuss the technical aspects of the product like the number of cavities necessary for optimum production, the amount of moulds needed for the components or if family moulds could be an option. Also discuss the raw material to use and product manufacturing time. Product assembling, packaging and transport should also be discussed.

4. Improve and finalize the design

It is very important to improve from what you have learned in the previous step. You can always print a sample by 3D print technology to ensure that you are happy with the end product and that it works for the intended use. The production price will be quoted by the plastic injection manufacturers and they will also have the right contacts for mould makers to request a quote from.

5. Sign off the design

Signing off the design after ensuring that you are happy with the final product is off utmost importance. Discuss this with the mould maker and pay the deposit for making the mould. The mould making normally takes around 12 weeks depending on the type of mould required.

6. The mould is now tested for accuracy and functionality

After the mould have been manufactured, tests are done on the plastic products to ensure that it produces correctly. A quality check should follow to confirm that you are happy with the end product. Look out for flashes, short moulding, burn marks, vacuum voids and sink marks.

7. Final delivery to the plastic injection moulder

Some last checks and amendments can be done by mould maker before final delivery to the plastic injection moulder where production will take place.

8. Place your orders

Now it is time to confirm your order for your plastic contract moulding product by specifying materials, colours, amounts and delivery times.

9. Production takes place

Production now takes place according to your order in the lead time as discussed. Assembly takes place if necessary. Product is then packaged as specified.

10. Delivery of end product takes place.

Depending on what the plastic product/ component is, you can now utilise it or sell it as intended.
