Injection molding is highly preferred process to make plastic products usually solid ones. One f the main piece of equipment that use in injection molding process is the mold. In many cases, molds are the most expensive part of investment to manufacture a particular plastic component. Molds are very delicately designed and require precise characteristics and technique to assemble as a functional unit, these might be the reason of being expensive. Injection molded products can range from small to large sizes, and they are applicable in many industries. Automotive industry, beverage and food industry, medical industry, electrical industry, cosmetics are few examples where injection molded good are highly used.

In injection molding process, the raw molten plastic material is poured in the mold cavity with high pressure to settle down. The mold cavity is shaped in the hollow form that represents the configuration of the product to be made. The mold should be made with high precision and tolerance to withstand the molding conditions such as pressure, temperature, and clamping force require to hold the material at place. To get the plastic parts we want, it is necessary to make the manufacturing decision and with the design and construction of mold.

Here are main things that need to be the first consideration if you need the expected top-quality molds either a small sanitizer bottle cap mold or large bumper mold.

Mold material

The mold material is a prior consideration and choice of material depends on various factors. Cost-efficiency and product specification are two of the factors that would affect your choice of material. Complexity of product design, volume of production, size of the product run highly influence the material choice.

• Aluminum is relatively less expensive mold construction material. It is best suited for injection molds performing low-volume production runs. Molds with simple shapes with low strength can be crafted out of aluminum. As the molds made of aluminum are not stronger their lifespan is reduced and not suitable for long term projects.

• Pre-hardened steel and hardened steel are other popular mold material construction. Pre-hardened steel is durable to withstand in wear and tear. It supports complex mold design better than aluminum material. Hardened steel is best suited for high-volume and long term runs mold. It is generally expensive mold material and stronger too.

Mold cavity

As we know that mold cavity is the hollow part of mold where the molten plastic is settled to take shape of the intended product design. Molds are categorized into single cavity and multi-cavity based on design. Multi-cavity molds offer higher volume rates than single cavity ones. Tooling cost of single-cavity mold has lower tooling cost but expenses can be high with reduced volume. With large volume production needs, multi-cavity mold should be preferred instead of single cavity.

A trusted manufacturer should be hired for the mold manufacturing process. With a typical procedure to mold making considering all the required specifications and test for quality construction, your mold would be ready. For mold making services, visit http://www.nicety-mould.com/
