You should consider using the injection moulding process if you are planning on manufacturing plastic parts or products. The technique is highly efficient, and it can produce items of high complexity. In addition, this method allows the production of products using a mixture of molten polymers for unique properties. The only potential drawback is the relatively high cost of parts production. However, you can use different measures to control your total expenses. Here are some designing tricks to help you minimise the total manufacturing costs.

Check Your Wall Thickness

You should choose the right wall thickness specifications for your plastic parts to promote optimal performance and ensure minimum costs. In general, you should first determine the minimum thickness for your products which will meet the desired standards. Thinner walls will use less manufacturing resin, reducing your material expenses. However, you should know that a thinner wall will need easier flowing plastics. Next, you should check the uniformity of your walls. You can order plastic products with varying wall thicknesses. However, they are more complex and more expensive to manufacture.

Reduce Part Undercuts

When designing your plastic part, you should reduce the undercuts in your potential products or completely eliminate them. These features can increase the complexity of your designed item significantly, and the costs of manufacturing will increase significantly. In injection moulding, an undercut can be defined as a feature in the design which cannot be incorporated using a single mould. The undercut can be added to a product by including special holes or snaps in the design. However, if possible, you should not have these complex features. Instead, you should discuss a design change with your fabricator or designer.

Manage Your Finishes

Finally, you should think about the necessity of cosmetic finishes and the level of finishing required for your product. The finishes can include textures and patterns on the surface of the designed product or other patterns which change the appearance parts. Under normal circumstances, you should only incorporate finishes which add value to the final product. For example, ribs and other special textures can strengthen containers and reduce the rate of wear. If your product must be appealing, you should consider additional finishing processes. For example, you can have the tooling marks removed through polishing procedures. You can also texture the surface for special appearance characteristics. However, the additional work will mean increased costs. Therefore, you should evaluate the need for enhancement with care before proceeding.
