Injection Molding

Injection Molding is a process that is commonly used for manufacturing parts. It can be performed by hand for custom projects or performed with an injection molder machine. The machines are often used for large quantity orders of parts.

Injection molding begins with the melting of a chosen material. Once a liquid has formed, it can be injected into a particular mold design. After cooling, the product may be removed from the mold.

Molding is used for many industries including medical, electronic, telecommunication, automotive, and consumer applications. As technology advances, equipment tends to miniaturize. Therefore, micro injection molding, for miniature parts, continually grows in popularity with each passing day.

Saving Money in the Process

There are various materials to choose from for injection molding. Plastic tends to be the most popular material. Plastic is desirable because it is versatile and low in cost.

Injection molding machines are very quick and precise with their work. However, they are extremely expensive to purchase. You may want to obtain contract manufacturing services to help you produce parts if you cannot afford to purchase a machine.

Another alternative to saving money on the purchase of a machine is by creating smaller parts. Smaller parts can be created with a micro molding machine which is less expensive than the larger models. By creating smaller parts, you will also save money on the cost of materials.

Injection Molding Product Solutions

When creating a molded product, there are certain factors that may affect the longevity of the product. Many products may be exposed to hazards such as ESD (Electro Static Discharge), RFI (Radio Frequency Interference), and EMI (Electro-Magnetic Interference). These hazards can be avoided with shields or coatings that will protect the product from any interference.

Shields or coatings are available in a few different forms. You can use tapes, foams, gaskets, or films. You can also package your parts in anti-static, conductive plastic bags to preserve your products and to make them presentable to buyers.
