All You Need To Know About Plastic Moulding

We cannot imagine a world without plastics. Plastics have found their importance in almost all application ranging from household items to complicated research equipments. Though there were controversies that the plastics pose a threat to the environment, the advancements in plastic manufacturing technologies have given birth to the eco-friendly plastics. Plastic manufacturers can now recycle and create new plastic products out of the used plastics. You will be well aware of the fact that injection moulding is widely used to manufacture the plastic products. Today’s plastic moulding is very much advanced and very different from what was originally invented. Just keep on reading the article to know all about the plastic moulding techniques.

A Little History

Plastic moulding is not a new concept developed in the 21st century. Moulding plastics into useful products exits since the origin of manmade plastic in the year 1851. The process of heating plastics and melting the molten material to obtain the shape of the mould is the basic concept behind plastic moulding. Though the concept of plastic moulding remains the same today, this technology has seen many advancements. Plastic moulding received huge importance during the period of Second World War due to the demand for the plastic medical equipments. Infact the plastic manufacturers where struggling to meet the demand for the plastic products during this period. This is period when the plastic moulding industry got a new shift towards development.

Current Plastic Moulding Techniques

Though the main concept of plastic moulding remains the same, the equipments used by the plastic manufacturers have changed a lot. With the integration of latest computer technologies the production rate of plastic moulding is greatly increased today. Unlike the olden days only when only fresh plastic materials were moulded to useful products, today with environmental awareness on the rise, plastic moulding concentrates on using recycled materials. Moreover, the advancements in plastic moulding technology has made it possible to manufacture products in any complicated shapes.

The Applications Of Modern Plastic Moulding

The applications of plastic injection moulding are virtually unlimited. Starting from simple plastic carry bags to complicated lifesaving devices – every plastic product manufactured today are through plastic injection moulding. Some of the common applications of plastic moulding are the manufacturing of products such as packaging bags, automobile parts, beverage cans and bottles, computer accessories etc.

The Future Of Plastic Moulding

You will be well aware of the fact that the use of plastics is banned in certain areas of all countries. People think that this may end the plastic manufacturing as environmental pollution is a major concern today. However, with the introduction of the recyclable plastics, the plastic industry has got a rebirth. Afterall, as already said, we cannot imagine a world without plastics.

Question by Josh W: Anyone know anything about Plastic Injection Molding?
I’ve been designing a little invention that I’m trying to get made and possibly mass produced, but I don’t know the first thing about how to do so. I’d like to get at least one made so I can tweak the design until I get it just right, but where do I start? Do I need to create a computer model in order to get a mold made? How large of an investment am I looking at? Any information would be appreciated.

For prototypes, you could go to a machine shop with a drawing and ask them to quote on machining it out of aluminum or brass. If you are planning on getting a patent or trademark on your invention, you should consult a patent attorney about how to protect your invention. Having an injection molding die built will be expensive (depending on the details of the design). There are a number of technologies around for rapid prototyping. This would be similar to the machine shop route but would give you an article in plastic (or epoxy or wax or ??? depending on the technology) and it should be cheaper. Either way, you will need drawings with enough detail for someone to make it. If it is not too complicated, you might be able to build a scale model (either larger or smaller) using materials from the hardware store or building supply (styrofoam insulation, PVC pipe, wood, or others).

Search on rapid prototyping and talk to some local machine shops. On the plus side, your local machine shops are probably anxious to get the work. You may be able to protect the invention by having three different machine shops each make a few different components if you do not give them the entire drawing. good luck
