How Custom Injection Molding Enhance Productivity In Manufacturing Companies

By Michelle Johnson


In the lyrics of the song Barbie Girl there is a line where the singer says that living a life in a plastic world is fantastic. It is true that in life imagination is all you need to create, and in our modern market today there are more plastics being produced for people to use and thrown away. Though it may cause considerable harm to the environment but it is one biggest industry around the world.

However manufacturers who supply products that are made from plastic need to be able to satiate this demand in the fastest way possible. From this reason alone it is imperative manufacturers find suppliers of custom injection molding equipment. However investing on these machines are very expensive and the requires most companies to hire an engineer who can manage the process.

Furthermore the machine itself could produce larger volumes of production than using human labor. However molding one require the intervention of a specialize tool to produce the right design and reduce the occurrence of defects during the process. Because molding plastic undergoes several short stages to produce high quality objects manufacturers must take the risk to invest in it.

Manufacturers are often wondering whether to use molding tools for their products or not. Because buying one requires investing thousands or millions of dollars. But on one hand it improves the productivity of the work area.

Plastic is poured into a clamp, the plastic must be in pellet form. And the clamp must be tightly secured to keep the molten liquid from escaping. Pressure and heat are applied in the mold then after some time the clamp is opened to release the finished product.

Each cycle lasts for about two minutes or seconds, and the maximum wall thickness is decreased each time to lower the cycle time. About the design rules plastics with thin and uniform walls are highly acceptable than too thick or non uniform walls. Some rules in design are corners, draft, ribs, bosses, undercuts, and threads.

However business owners should know that a competent engineer is needed to oversee the production. They must be able to identify the causes of common defects to adjust the machine and to improve each cycle. There are six known defects called bubbles, warping, flash, unfilled sections, ejector, and sink marks. Each have a corresponding cause, for example sink marks, when there is insufficient injection pressure and cooling rate is not uniform thus this defect happens.

Moving on the plastics industry is an industry that has the highest revenue around the world. This shows that this is simply part of our modern society, so this means that plastic is an indispensable. However for many growing companies who want to expand their businesses and increase the work flow then investing on molding equipment should be considered.

But the cost of each tool highly depends on the parts being produced. Because the mold and cavities depend on the design, so if the parts needed to be produce is large and complicated. Then companies will need to invest on large expensive mold bases and cavities.
