What Is Mold Making?


Mold making is a manufacturing process that involves shaping a raw material through a fixed frame, which is known as a mold. The mold is derived from a specific pattern. As the liquid that is poured inside the mold cools down and solidifies, it is removed. The main objective of mold making is to replicate multiple uniform copies of a product.

Injection molding is one of the most popular types of mold making for silicone, rubber, thermoplastic, or liquified raw material items. With this process, the mold is placed inside the injection molding machine, then the liquefied raw material is poured. Once the material becomes solid, the final product is ejected and the process is repeated for large series production.

Types Of Mold We Make


Richfields is a plastic mold maker that can produce a wide range of mold types. Inside our manufacturing facilities, we have 22 units of injection machines with sizes ranging from 50 tons to 2,100 tons. These include units for CNC, EDM, Wire Cutting, Lathe, CMM, Milling, Hot-Stamping, Pad Printing, And Silk Screening.

From insert molding, overmolding, to unscrewing molds, Richfields can mass-produce the molds you need for your project.

Multi-cavity molds or high cavitation tool

Multi-cavity molds have more than one cavity, or hollow spaces, cut into the mold. Unlike single cavity molds that produce only one item per cycle, multi-cavity molds produce more items per cycle. As a result, multi-cavity molds provide a shorter lead time. These result in the faster completion of more parts from the same mold.

As a top plastic mold maker, our team at Richfields recommends multi-cavity molds for clients that need increased molding capacity and lower piece costs. Our multi-cavity parts molds maintain precision and optimize cycle times.

Family Molds

Family molds are similar to multi-cavity molds because these have more than one cavity in a single mold base. However, their cavities come in different shapes and sizes, making them ideal for prototypes.

At Richfield, we recommend this type of mold for clients that require cost-efficiency and product variation.

Overmolding

Overmolding is a unique type of molding process wherein two or more materials are molded on top of each other. This is the recommended mold type when the product design calls to combine multiple materials with different specifications.

As your plastic mold maker, we will utilize this when two-shot molding is needed to meet the complexity of the product. Rest assured our team is trained to be precise when it comes to overmolding.

Hot Runner Molds

Hot runner molds consist of two plates that use a temperature-controlled manifest system. Here, heated components are used to inject molten plastic into the cavities of the mold. As a result, hot runner mold greatly reduces runner scrap from the cycle.

As a reputable plastic mold maker, Richfields also has the capabilities to produce hot runner molds. Our hot runner molds benefit clients looking to avoid wastage in cycle times and labor cost, while guaranteeing high-quality plastic products.

Cold runner molds

Cold runner molds consist of two or more plates that also use a temperature-controlled manifest system. The molten plastic is injected into the cavities of the mold. Here, the runners cool the runner, sprue, and gate along with mold products.

Similar to hot runner molds, Richfields also creates plastic cold runner molds. Cold runner molds have been widely used for molding due to their cost-effectiveness and ability to accomodate design alterations.

Unscrewing molds

Unscrewing molds are used to produce threaded products. As a prime plastic mold maker, Richfields Corporation has decades of experience producing unscrewing plastic injection molds. Unscrewing molds are recommended for clients that require high volume output, while minimizing damage on threads of plastic parts.
