7 Tips to Reduce the Copy of Plastic Injection Molding Costs
In the last few years, plastics have displayed greater promise in manufacturing than metal. As a result, we will likely see an increase in the number of tools using plastics.
Here are some great tips to ensure that your organization’s costs remain as low as possible:
Simplify your design
It is not necessary to make a complex, fully dimensioned drawing to design a mould. A simple sketch and word description of each part with the part print can serve as the first step in cost reduction just by reducing CAD work and costs with several simple processes.
To make drill jigs used to make holes in shaped sheet metal parts from glass-reinforced plastic (GRP) laminates, one part of the sample part is usually made after the holes are all drilled in their correct location on the part. There are many kinds of instructions that can be provided for using this tool, whether it is a free-hand sketch or written instructions that specify the part dimensions and quantities of drill bushings that must be used.
Utilize parts or models which are already available
Essentially, plastics can be described as a replicating material. Because of this, a form is always required, except in special circumstances, such as loft template constructions. The fastest method for replicating a part in plastic is to begin by working with an existing design, such as a model or prototype, and mimicking that design with plastic.
Build new models that are male shaped
When designing a master model, build it in a way that allows for the quickest duplication (which is most common in a male shape) and on the side of metal that requires the minimal amount of thickness transference.
Adopt flat runs-outs
In maximizing the practicality of flat run-outs, most engineers strongly advise using them once constructed, as they provide the simplest possible way to construct their structures.
We want to advise any team member to simplify the reproduction process by removing all undercuts and loose pieces where possible and simplify the process of replicating shapes with plastics by removing all undercuts and loose fragments.
Adopt lattice-type laminates
Lattice-type laminate structures are almost always better than solid structures. This is because they employ fewer materials, require less labor, and weigh less than solid structures.
Choose supporting structures wisely.
Every type of support structure has its advantages and disadvantages based on how each type of tool is adapted. Wood has the benefits of lightness and low cost, but it does suffer from unreliable dimensional stability. Cast iron is the closest thing to wood in terms of price, and it is readily available, but it can require lengthy, costly machining to turn it into a finished product. Aluminum casts are more expensive than cast iron but can usually be ordered more rapidly and can be machined to a point quicker than iron. Cast steel has the highest strength, costing more and taking a long time to manufacture than other metals.
Fabricated plastic components can bear significant losses due to both the cost of components and the labor incurred. Still, they also offer advantages in terms of size and weight.
Generally, where large quantities of plastics are required without their strengths, fillers can be used to increase the performance of the plastics materials that are relatively costly.
