Hard tolling is however costly to fabricate. We require to utilize precision machining at times to enhance the molds made. We also exercise a great deal of care while fabricating to avoid any costly errors.

In hard tooling, we use studier materials to make the molds. Examples of such material include steel alloys, aluminum, and nickel. The molds notably take longer to make and design thus raising their cost when compared to molds for soft tooling. However, molds made from hard tooling last longer in use. This makes it hard tooling the ideal option for producing high volumes of parts.

The entire process involves injecting molten material using an injection molding machine into the cavity. The process is more automatic when you compare to soft tooling injection molding. The curing process is shorter in this scenario, taking between a few seconds to a few minutes. Not only does this help in yielding parts quicker, but it also makes more parts within the specific duration of time.

There exist two broad classifications of injection molding tools namely hard tooling and soft tooling. At Creatingway, we realize the importance of selecting the appropriate tooling process in order to get properly functioning parts. This is entirely dependent on specific factors affecting the injection molding process. They include material selection, budget constraints, and volume needs.

Clients that require quickly produced molds should consider soft tooling rather than hard tooling. A hard tool mold takes a week to make while a soft tool mold takes only a few days. It is still dependent on the complexity of the design.

The entire process involves injecting the molten material manually into the mold cavity through a tube. It takes about 3 to 24 hours to cure. This is dependent on the type of material injected. After the curing process is complete, we open up the molds manually. If the parts made require any additional finishes, we subject it to secondary processes. This ensures we deliver properly functioning parts.

In soft tooling, we use molds made from fiberglass, silicon, or carbon fiber. It is generally good for producing urethane castings and rubber moldings. Each mold cavity is reusable for about 30 to 50 cycles of injection molding shots. This makes soft tooling well suited in the production of low volume parts.

The key difference between hard tooling and soft tooling is the type of material we use in producing different molds. Hard tooling uses aluminum or steel to produce parts from injection molding. On the other hand, soft tooling uses silicone to produce parts from injection molding. Here is a further insight into how to distinguish the two injection molding tooling processes. It will additionally assist you in knowing which is within your budget, produce properly functioning parts, and will help you keep time in your project.

The More complex design is, the higher the cost in making the mold. Unless absolutely necessary, keep the design as simple as possible.

Hard tooling molds have longer tool life thus making more parts. Soft tooling, however, has a shorter tool life thus making low volumes of parts.
