Custom Injection Molding
Custom injection molding involves the process of injecting materials that are molten by heat into a molding tool to produce parts. The materials and produced parts are generally plastic, and are used in many product industries. It is a core manufacturing technology for the mass-production of identical parts.
For example, a custom injection mold which can be seen in the image below, is a specifically made part usually made from steel, aluminium or other metal alloys and is a critical part of the custom injection molding process.
A custom plastic injection molding definition would be similar, with custom plastic injection molding, these molds can produce thousands of plastic parts over the course of its lifetime.
The key understanding of custom injection molding is just how exact custom injection molding specifications need to be. It’s vital that an injection molder understands and aligns with the needs of your product, since parts that are used in certain fields – like medical or military – vary greatly when compared to foods containers or toys. This demands attention from professionals who are truly well versed in complex designs and compliance from a custom plastic injection molding company must be strictly adhered to.
What Is The Custom Injection Molding Process?
When it comes to injection molding custom, there is generally three significant steps in the process: they involve product design, mold design and the manufacturing process.
The design process also happens to be one of the most important processes, since it is a great early opportunity to prevent any expensive mistakes from happening later. Function, assembly, manufacturability and aesthetics all play an important key role in determining the product design process and the right design is one that accomplishes your objectives to a satisfactory level. The product design stage is usually accomplished with a CAD software, which stands for computer aided design. In order to engineer custom injection molding, skilled engineers will brainstorm, design and improve a variety of issues surrounding the particular product at this stage.
See below for an image of a product during its design process on CAD software:
Once an image has been designed, the next step is to design the mold for injection mold manufacturing. Generally the mold is made of steel, aluminium or other metal alloys. Mold design, similar to product design, is another great opportunity to prevent any defects during the custom injection molding process.
This is an image of a mold being developed during its design stage:
The final stage is the manufacturing process. Once a product has been designed, approved by the team and cast, it’s time for the actual manufacturing. This is when the custom injection molding plastic is heated and poured into the plastic injection mold, by way of a custom injection molding machine. Once cooled the mold is opened and the part ejected. Any excess is sheared off automatically and manually removed. This cycle can repeat, even hundreds of thousands of times in only just a short space of time.
For such a complex process the whole undertaking is both impressive and swift. It’s no wonder such a thing is the go-to for creating custom injection molding parts.
How Much Does Custom Injection Molding Cost?
That depends. I’m sure that’s not a very satisfying answer but really, it’s possible you’ve seen plenty of custom injection molding services from many custom injection molding companies and they all say the same thing, “Request a quote”. Why? Because there’s no one size fits all philosophy in the way of a custom injection molding cost. There are too many variables, such as the size of the product, its material, the material of the mold itself (for example a steel mold is more expensive but can make significantly more parts than an aluminium one), how many parts do you want to make, how detailed or simple is the design. What about the location of the manufacturer? They too, will expect different price points. With all these variables and much more, is there any surprise the company would like to know more details about your product first in order to better accommodate you and your needs?
