The New Age of Tool Design and Custom Manufacturing

When it comes to procuring functional parts and implements in this day and age, plastic injection moulding is quickly becoming the most cost-effective and versatile method of manufacturing durable products.

In its simplest form, plastic injection moulding involves shaping and sculpting heated synthetic materials to create tools, replacement parts, toys, and a wide array of other plastic-based items. The actual step-by-step process is shown below:

  1. ABS, polypropylene, polyoxymethylene, or any number of other synthetic materials are fed into a heated container.
  2. The materials are mixed together to ensure a uniform blend.
  3. The resulting mixture is poured into a mould cavity.
  4. In a relatively short period of time, the plastic mixture hardens and takes the shape of the desired final product.
  5. After hardening, the product can be reworked, remoulded, or added into a separate manufacturing process.

If you happen to be in the market for toolmaking in Melbourne, for instance, you’d be best served by taking a long and hard look your local plastic injection firms before you partner with any particular company. This brief article will help you understand the process of injection moulding and describe how to go about finding the best local manufacturer in your proximity.

The Benefits of Plastic Injection Moulding

When compared to alternative plastic processing options such as 3D printing or plastic machining, it’s important to note that plastic injection moulding comes with a host of advantages and benefits over the competition:

  • Exactness: Provided that plastic injection moulding is accurate within .02 centimetres in most applications, it trounces the competition in terms of precision.
  • Speed: Although the manufacturing speed depends on the intricacy of the mould in question, plastic injection tooling requires only about 15-30 seconds of downtime between cycles, which allows you to produce a lot of parts in a short period of time.
  • Low Labour Expenditure: Due to the inclusion of a self-gating automatic process, plastic injection manufacturing requires little to no supervision on a running basis. Thus, moulding specialists are able to save quite a bit of money on overhead costs and labour fees, which is effectively passed down to the customer in the form of an inexpensive final product.

Picking the Best Local Supplier

If you’ve been using a 3D printing service, die-casting company, or plastic machinist to procure your parts up until now, you’ll have to conduct some research in order to find a reliable plastic injection firm in your area because it’s a very nuanced, specialised field. With this notion in mind, feel free to use the checklist below to help you distinguish the contenders from the pretenders:

  • 25+ years of experience specifically with plastic injection moulding.
  • Comprehensive quotes that are easy to obtain online or by phone.
  • ISO 9001:2000 certified, which means that the firm in question consistently meets regulatory requirements and consumer demands.
  • 3D CAD design capabilities.
  • Ability to perform HS CNC machining.

If you find a company in your area that fits the above criteria, you can rest easy knowing that your upcoming toolmaking project will be in the best of hands.
