Plastic Mold Basics

Plastic is one of the most used materials in the manufacturing of toys, tools, and other consumer goods. It’s very name, ‘Plastic’, from the Greek ‘plastos’ refers to ‘molded’. It is clear that the material plastic’s real value lies in the ways in which it is used and Plastic Mold. Plastic is extremely malleable, and allows or it to be pressed, extruded, cast, or molded into many different shapes and forms.

Plastics are used in a wide range of rapid prototype products, from every day office products such as pens, clips, and printers, to high-end uses such as TV’s, stadiums, and space shuttles. Before plastic’s wide adoption across many different industries, other materials such as wood, stone, glass, ceramic, and leather were the standard products used. Now, to find products made of leather and stone indicates a certain quality and ‘rareness’ because most of our ’stuff’ is plastic. Plastic has displaces all of these traditional materials and is now the dominant material in all of manufacturing.

The drawbacks to using plastic stem from its chemical makeup. The compounds comprising rapid prototype limit its ability to withstand heat and makes it vulnerable to hard impacts and weight. Plastics are limited in how dense and hard they can be made to be which causes many of these weaknesses. Additionally, plastics are not highly conductive of electricity, and so they are limited in use around electronic components. Additionally, the price of plastic molding and work limits its use as a building material (aside from PVC) in construction projects because it is still to expensive when compared to working with concrete and lumber.

Polyvinyl Choloride is an extremely useful plastic. Commonly referred to as PVC, it is used heavily in plumbing but also has many practical uses such as framing out large shapes and many other uses where tubing is involved. It other forms, PVC can be used in rain gear, packaging of food, shrink wrap, home siding, computer enclosures, and many other places in which most people don’t expect.

Plastic has truly revolutionized how the world operates. We now can have many tools and utensils because they can be developed and manufactured very cheaply with plastic. If plastic were not around, many of our standard household items would have to be made out of more expensive materials, thus limiting the ability for most people to obtain them. Plastic is cheap, extremely malleable, and very stable, and thus has many different uses which people all over the world have researched and continue to research to push the possibilities of plastic.

Question by davidvu2007: Plastic mold injection: approximately how much it cost?
I want to produce something like this:
http://youremblem.com/images/samples/3.jpg

The letters are separate and are chrome plated. How much would it cost to produce and chrome plate 500 letter assuming it is 1x2x.25 inch and are made of plastic?

Answer by tlbs101
Setup charges are the ‘killer’ to a small project like this. The per-letter cost will be pennies, but it will cost several thousand US$ as a setup charge.

The injection molding company *may* have a standard letter-set mold in stock, so that may save a bundle. You’d have to check with each company to find out if they have letters in stock. Be sure and ask if they do the chrome plating, too.

Even if they have a set of letter molds on-the-shelf, they may charge a minimum that will run in the US00’s.

Question by Skt: Plastic injection mold – cost estimate?
I think most of you would have seen the SD-card case, the clear plastic one, ~ 2″ x 1.5″ x 0.5″. I don’t know if I can post web links, here is one sample image,

http://www.inanycase.com/Merchant2/graphics/00000001/SDMMC-Card-Case0405_thumb.jpg

Can any one give me a ballpark number for how much the injection molding would cost for a product like that? In the US vs in China?

Thanks.

Answer by tinkertailorcandlestickmaker
High production multi-cavity hardened steel, or low production, single cavity aluminum (or maybe even epoxy)?

Since cases are already available, I’m guessing you might want a limited run with a special logo for some promotional use. But then again you ask about China…

I don’t really know, but I’d guess several thousand for the first case, and a few to several hundred for the second case (US dollars)

But if you can sell the cases for .33 each (3 for .99) you should get your money back pretty quick. Of course that is a really big IF, I wonder if inanycase.com has ever sold any of those cases at that price? that seems insanely high. I could believe 12 for .99 (not that anyone would need 12, since most cards come in a case to start with)

Question by Eidelberg: how do i creat plastic injection mold?
and when i do create it how do i use it?

Best answer:

Answer by virtualguy92107
An injection mold is two steel or aluminum plates with the shape that you want to create cut out of the metal, along with channels that allow the molten plastic to be forced into the mold. They are made with standard metal machining techniques. You use it by installing it into an injection molding machine, which means you have to know what model of machine you are building the mold to fit.

The Processible Plastic for Mold Making

1. Introduction
The processible plastic — Hongke material is a fundamental casting material with high density, high precision and high stability and is suitable for cutting in high speed. It is widely used abroad in aviation, navigation stage properties, and electrical appliance where high quality mold and module are required.
Concurrently, only few countries in the world are able to produce this kind of processible plastic. With the development of high technology, the demand for high quality mold with a complicated curve shape, and difficult technique in manufacturing is increasing, As a result of their own limitation, the traditional casting material such as plaster, paraffin and wood etc, can not realize CNC numerical control rnanufactuimg and satisfy the need for development. Therefore the processible plastic replaces the primeval mold making material. Particularly in the 90’s, with rhe spread of numerical control manufacturing technique, the phenomenon is even more outstanding. In early 80’s, similar materials has been invented for smiuktmg cutting arid mold making on numerical control machine, but in our country this kmd of material relied totally on import until 1997. This fully demonstrated the importance of this kind of material for our mold making industry. For example mold making,casting mould,plastic injection mold etc.According to statistics, till April 1998, we have already 400 set of numerical control center (5 axises, 5 axises) of our mold making industry. It showed product simulating cutting requiring processible plastic. The demand is evident. As specified in 95 national plan, the annul output after 2000 of automobile will reach 2 million 7 hundred. Some 175 to 440 kinds of basic body type of automobile will leave for renovation and reform. The cycle for automobile type renewal is 6-10 years in our country. In the foreseen years the processible plastics will be used more extensively in life. Therefore the processible plastics – Hongke plastics is produced to meet the demand, its performance index has already reached the international standard for likewise products.

2. Develop of the product
At the moment, only few countries are able to manufacture processible plastics worldwide. Before 97, china has spent over tens of millions US dollars on this material. To produce and nationalized the material and to cut the cost and replace the import products become urgency. It’s a common knowledge that mold-making industry is the mother of modern industry. It is a significant symbol of industry development of the country. One cannot separate the development of mold material when talking about mold making. In the recent years, our mold making industry is transiting into modem industry development, CAD/CAM technique, numerical control manufacturing are widely used, consequently the requirement for the mold material is higher. Once a technician of a famous mold workshop discuss with us about producing a kind of basic casting material for high speed cutting on the numerical control machine, which should not be transfigured by the process,
of which the amount of abrasion of the knife should be low, and doesn’t absorb moisture
and is antisepsis, with a sufficient degree of finish on the surface^ and be preservable over
long-term. The factory is allocated with CAD/CAM technique together with advanced
numerical control manufacturing center. But the so-called ” processible material” has been
relied on import, which is expensive to buy and gives a long cycle for supplying. Hence we
made a survey over the mold making industry, and the result verified that the material has
a potential huge market. At that time, no such material was available nationwide, it is totally
relied on import. Therefore Honke material co. Ltd. began to engage itself on the research
and development of the material, during the formulation of the prescription, through
selecting various chemical structure of macromolecule to adjust, modify, and add ancillary
preparations and filling, can prepare double component mash like material and panel
material of different high and low density and performance index. When basal material is in
the basic system of macromolecule, add different modification monomer material of all
conditions, such as elasticizer, activator, and filling etc can greatly improve the
technical performance of the processibel material. Below is a brief description at initial period of matching the material and reaction procedure.
