What Is An Injection Mold Maker?

Molds can either be the fungus that eats up organic matter or a process that requires shaping a liquid form to an established shape. Molding is a process wherein a liquid form of glass, metal, ceramic or plastic is filled into a hollowed out block and it takes the shape of the block. Mold makers are what manufacturers or producers of the end products are called. These make the molds that are used to shape the plastics or metals which are melted. Injection mold makers are these that make molds specifically for injection process.

Uses of an Injection Mold Maker

Injection molding is what people call the process of filling an injection mold with liquid plastic and waiting for it to take shape. An injection mold maker is the machine that makes the mold for injection molding. An injection mold maker makes molds from metals, usually steel or aluminum. The process calls for precision because a mistake means a repeat of the process or the part made will not be ale to function well enough and may be substandard.

The process of injection molding relies solely on the accuracy of the injection mold maker. If the injection mold maker makes a mistake in making the necessary molds needed to produce plastic product, the over all effect will be defective. The mold maker must have the precise measurements of the mold it will make in order to fully meet the standards of the manufacturer and client.

Materials Used in Injection Molding

The usual materials used by injection molding are plastic materials like polystyrene, acrylonitrile butadiene styrene, nylon, polypropylene, polyethylene and PVC. These are the liquid plastics that are usually used by injection molds to produce the plastics that they will then sell. The polystyrene material is lower in cost and in material grade. ABS is a plastic that is hardier than the previous one but not flexible. Nylon can resist mot chemical and is more flexible the previous two. Polypropylene is the plastic usually used to manufacture containers because they are tough and flexible. Injection molding is also utilized for metal works.

An injection mold maker will have to make more molds if the molds are used for metal molding. Metal molding wears out the molds more than plastic molding because the melting temperature of metals is higher than plastics. Despite this additional cost, manufacturers still utilize injection molds for metal molding because the prices of metals that are molded this way are still profitable.
