Three Issues That Must Be Accounted for When Designing Injection Molding Tools

Working with a highly capable Singapore Contract Manufacturer can be a great way to produce parts and goods at affordable prices. For many of those who chose to make use of the services of a contract manufacturer today, the goal will be to employ the widely used technique of plastic injection molding.

Every such injection molding project will require the design and product of molds or tools whose characteristics determine those of the finished product. Understanding some of the types of issues that must normally be accounted for throughout these crucial stages of the precision moulding process will always be helpful.

Carefully, Thoughtfully Designed Tools Contribute to Success

While the injection process itself is fairly simple, problems of various kinds can certainly still arise. Many of the most common of these eventually end up being traced back to shortcomings or oversights related to the designs of the molds that are used as part of particular production runs.

There are many types of molding processes, some of which have been used widely for many years. While it will always be possible to set up an injection molding project so as to satisfy the associated requirements, a great deal of care must be taken with regard to the design and creation of molds. Some of the issues that must be considered and accounted for when injection molding is chosen instead of an alternative include:

Sprues. Molten plastic has to be introduced into finished tools carefully and so the passageways that allow for it will not impart undesirable characteristics into the finished product. The location and size of the sprues that are used to enable the introduction of plastic will always be an important consideration when designing molds.

Ejection pins. Injected parts will normally be removed from molds with the use of ejector pins that physically dislodge the parts. Each pin will typically leave a similarly sized mark on the surface of the part where contact is made. It will often be desirable to position these pins such that the blemishes they create will not detract unnecessarily from the appearance of the finished part.

Tool material. Molds can be made from any of a variety of materials, some of which might wear better or be easier to handle in certain situations. As a result, plenty of effort will normally be put into the selection of an appropriate tool material.
