Plastic injection molding tools are the critical capital assets used to create molded plastic parts. These tools are fabricated from tooling specific grades of steel and aluminum and provide the negative cavity space into which molten plastic is injected during production to form plastic parts.
A skilled design for manufacturing (DFM) team can significantly impact a product’s overall manufacturing costs, with the most significant impact coming from the upfront design process. DFM integrates the restrictions and possibilities of the injection molding process into the product from the beginning, enabling the design to be a cost-effective and high quality end-use solution.
Using injection molding, complex part designs can be manufactured in shorter lead times compared to other fabrication methods. This allows the product to get into the hands of customers more quickly, boosting speed to market. Injection molding also offers low unit costs, making it an economical choice for large volume production.
When selecting a plastic injection molder, there are many elements to consider beyond price. The lowest-priced quote may actually result in higher costs down the road if the tool experiences excessive wear or is unable to meet production targets.
To maximize the longevity of a plastic injection tool, manufacturers should choose a partner with a long-term view. A trusted partner will invest in the proper maintenance of the tool, utilizing non-abrasive cleaners and applying appropriate levels of lubrication to moving components like slides and ejector pins. This prevents excessive wear that can negatively impact the overall performance of the tool.
Injection molding is a great plastic injection molding tools manufacturing method for complex parts that require very tight tolerances. The plastic injection moulding process is perfect for parts with bosses, ribs, side cores and other features that would be impractical or impossible to make using other techniques such as machining or vacuum forming.
A plastic injection tool must be carefully designed and fabricated to ensure it produces high quality parts every time. A key aspect of this is ensuring the correct gating for the tooling. A gate is the point where a runner enters the cavity image, and it must be placed correctly to ensure the molten plastic is properly transferred from the runner to the cavities and cores.
Once the gating is finalized and the T1 samples are approved, the toolmaker can begin the process of polishing and texturing the aesthetic cavities on the tool. This is a 1-2 week process that involves using various textures to achieve the desired aesthetic.
Once the aesthetic finish is complete, a hardness test is conducted to confirm the quality of the tool and its components. Once the hardness is deemed acceptable, the tool is ready to be shipped to production. During production, automated alerts can be set up to inform production teams as soon as the quality of a part starts to deviate from its target, eliminating waste on the factory floor and cutting production time down to a minimum. This is especially important for high volume production runs of a new product launch. Report this page
