Plastic Fabrication: Understanding the Factors Influencing Injection Moulding Costs

If you are planning for a plastic manufacturing project, you should think about choosing the injection moulding process. This technique is beneficial because it uses molten plastic in specialty moulds to create custom products. This procedure allows the creation of items with detailed structural features and intricate geometry. Also, different plastics can be used together and additives can be incorporated to produce special performance properties. However, you should note that injection moulding can be relatively expensive. If you would like to manage your budget efficiently and control the expenses, you must understand the factors which will determine the total costs of your plastic fabrication project.

Choice of Plastic Resin

There are numerous types of polymers in the market which are suitable for fabricating custom products. Each of these materials has unique performance properties and, consequently, the cost of the plastic is different. When planning for your manufacturing project, you should be careful when making your resin selection, especially if you are working with a limited business budget. Ideally, you should discuss your requirements for the product you wish to manufacture with regard to issues such as mechanical stability, chemical resistance and temperature resistance. You should find the resin which matches your needs. Do not select one with exceptional properties which are irrelevant to your item. This selection method will help you obtain high-quality goods without going over-budget.

Design of the Product

The specific design of your custom plastic product will determine the cost of your fabrication project. In simple terms, some manufacturing blueprints are easier to translate into moulds and manufacture into real items. If your design is intricate with numerous challenging aspects, the project will cost more. This higher price can be attributed to the need for better tooling for the creation of the manufacturing mould. You should consider simplifying the details of your custom product design to reduce your expenses. In some cases, a small complicated fabrication can be more expensive than a large simple one.

Allowed Tolerances

You should think about the tolerances for your custom plastic product when making your order. The tolerance refers the accuracy of the dimensions of the manufactured part or item. In some special cases, high degree of accuracy or tight tolerance is essential for a plastic product. For example, a polymer part manufactured for installation into equipment might need to have minimal error in measurements. However, if tight tolerances are not critical for your needs, you should not insist on accuracy. This aspect demands secondary manufacturing process which increase costs.
