If your current or next product is plastic-based, it’s important that you find a reputable mould manufacturer or otherwise known as tool and die maker. Plastic is the chief component in numerous products in today’s world. Whether it’s a shampoo bottle, a syringe casing, a smartphone cover, car components or something as simple as a pen, plastic is required in almost all such products.
When it comes to manufacturing a lot of these products, a mould for use in an injection moulding machine is what is needed. Here’s more on what exactly such mould is and why you need to choose a local manufacturer for your next plastic product.
When it comes to plastic products that have a complex design, or require high volume production, one cannot possibly manufacture them by simply assembling parts together. For such products, using an injection mould is the best way to go. Once the design of the product is finalized (normally by an industrial designer who uses software like CAD), the design can be used for production of parts. But there’s a crucial step first. A mould must be manufactured.
What is a mould?
Typical injection moulds are constructed from hardened steel, pre-hardened steel or aluminium. Steel moulds cost more to construct, but they have a longer lifespan. Pre-hardened steel moulds are less wear-resistant and are used for lower volume requirements or larger components. Hardened steel moulds are heat treated after machining. These are more wear-resistant and have a longer lifespan. The moulds are manufactured either by CNC machining or by using electrical discharge machining processes.
Moulds are made by a mould-maker or toolmaker. They are precision-machined to form the features of the desired part. Injection moulding is widely used for manufacturing a variety of parts and for high volumes, from the smallest components to entire body panels of cars. A mould consists of two primary components, the injection mould (A plate) and the ejector mould (B plate).
Using the specifications of the designed product, the mould is drawn up first and then the steel mould is manufactured. The most crucial part of this process is the accurate preparation of these moulds. If a slight miscalculation takes place when drawing or preparing the mould, you will get a completely faulty product on the other end. It is thus super important for you to choose a mould manufacturer that is experienced and skilled at the job. Precision is everything. The number of cavities incorporated into a mould directly correlates to the moulding cost. Fewer cavities requires far less tooling work, so limiting the number of cavities lowers initial manufacturing costs to build an injection mould.
Benefits of choosing a local injection mould manufacturer:
Reduced shipping costs
Transporting moulds can be an expensive task. However, when you choose to go with a local mould manufacturer, shipping costs are almost non-existent. The mould merely gets delivered to an injection moulding plant by road or rail.
Decreased manufacturing time
Now, when moulds are manufactured and shipped locally, you don’t have to wait for a long time to get started on product manufacturing. This way, you not only reduce the costs of manufacturing but also get your products made faster. In turn, this means that your products will hit the market sooner, allowing you to turn better profits.
Faster customer service and sign-off process
Your local mould manufacturer will be able to provide you with any query resolution much faster than an international mould manufacturer would. Also the sample sign-off process ( T1 and T2 samples) can be handled much quicker locally than if international which again requires shipping time.
Encouraging local profitability
Choosing a local mould manufacturer goes a long way in doing your bit to add to your own country’s economy. This is a great way to give a boost to local talent and encourage local profitability.
