Plastics molders form plastic into molds to be used for various purposes. This process may also be referred to as plastics extrusion, designed for high-volume manufacturing processes. Raw plastic material is melted and formed into a shape, resulting in tubes, pipes and even window frames. Familiarize yourself with these important terms about plastics molders:
Plastics Extrusion: High volume manufacturing process where raw plastic is melted, then formed into anything from pipes and tubing to weather stripping and fencing. It can also be used to make deck railings, plastic films, coatings and wire insulation.
Polymer: A large molecule made up of repeating structural units, bound by covalent chemical bonds. Many people refer to polymers as plastics, although the term covers many compounds of natural and synthetic nature.
Thermoforming: Plastic production process designed for thin and heavy gauge plastic applications. This involves a vacuum pulling a sheet of plastic over a heated mold, which then cools and helps to separate the plastic from the mold.
Injection Molding: Technologically advanced injection molding equipment creates components from thermoplastic and thermosetting plastic materials. Services in this realm range from design assistance to rapid prototyping. The material is placed into the mold by a heated barrel, where it cools and takes on the desired form.
Hot Stamping: A process used when a stamp is applied for decoration or function. This occurs on the plastic material while it is still hot.
Thermal Insulation: The reduction in heat transfer between objects near radiative components. This term refers to the maintenance of a temperature gradient through insulation where heat flow is reduced.
Plastic mold engineering companies are available to help you with the success of the product you're looking to sell. When it comes to the product itself or the packaging of it you will find that there are many different companies offering various services using different materials. You can look online or in a phone book to find an engineering company that specializes in plastic products. Custom orders are encouraged so everyone is given a product that was made especially for them. There are different processes that can be used, including slush and slurry. Blow, isostatic, sand, and dip plastic molding will give you different results. No matter what you choose you will want to be sure it passes inspection. Rolling, forging, forming, pressing, bending, and shearing plastic molds use different materials and machinery to achieve the desired design. Thermoplastics will range in price depending on the materials used and the company you choose to work with. Call several companies and ask about their rates. If you want to make containers using thermoplastics you will find that custom orders are more expensive than if you choose something they have already developed. Some companies will specialize making custom medical devices while others will do more with making containers using injection molds. Do some research on different choices and process, including the costs of hot runner systems, casting, compression molding and the difference between using plastic and rubber. Let the company know what you're looking for. Shells can be made for different products. Ask for a full description of what is involved when doing injection molding. Ask to learn about taxonomy and what is involved with permanent molds.
