Proto Type Injection Molding Services

In various contexts, such as prototypes and production, plastic injection molding is often necessary. However, this process usually consumes a high amount of resources and time. In most cases, this method is not suitable for everyone. The injection molding process is similar to series production, but it uses a tool adapted to the exact specifications of the project. This allows you to produce qualitative parts in a timely manner and at a low cost. We will introduce you to some advantages and limitations of this prototype mold technology so that you can make an informed choice.

Advantages and limitations of Proto Type Injection Molding


In various contexts, such as prototypes and production, plastic injection molding is often necessary. However, this process usually consumes a high amount of resources and time. In most cases, this method is not suitable for everyone. The injection molding process is similar to series production, but it uses a tool adapted to the exact specifications of the project. This allows you to produce qualitative parts in a timely manner and at a low cost. We will introduce you to some advantages and limitations of this prototype mold technology so that you can make an informed choice.


Definition and concept

A prototype mold is a type of plastic mold that is designed to produce plastic prototypes and small to medium series parts. Its economical and quick production method can be utilized for the rapid production of these components. This method is used for producing small series or samples. The advantages of this method are its fast production times and lower life cycle. The injected part properties are identical to those of a series mold. However, the life span of the injected part is reduced.


Advantages of injection prototype molds

This material is mainly made out of aluminum or soft metal alloy and can reduce the concept risk greatly. This material is also easier to machine than metal. This makes it easier to modify the cavities if needed. It saves a lot of time and helps in the development of new pilot and transition series. The faster the mold manufacturing process, the better the parts are produced in a shorter amount of time. Usually, these components are made to last for around 2-4 weeks. In addition, it can also be faster than a machine due to its complexity. It can also polish better than steel series molds. it would also be 20%-40% faster than a machine and 5-10 times faster to polish than steel series molds. That’s an interesting solution to increase speed.


Go for a prototype mold instead of a plastic injection one: this method will allow you to produce thousands of plastic parts in a short time. It's also less expensive than plastic injection. This mold can produce several thousand parts in a short timescale. It can also be used to make fragmented plastic parts. The advantages of this prototype mold are: it allows the injection of series parts, which are similar to series parts. It is also easy to over mold and insert molding.


Limitation of injection prototype molds

Most expensive prototyping technologies involve higher costs than other methods. Aside from the equipment and skilled labor, the cost of production also includes the injection materials and the labor costs.The cost for equipment (injection molding machines, machining equipment) and skilled labor is greater, as well as the cost of the injection materials.


Although it's quicker than traditional injection molding, it still requires a bit of manual work to get started. Some of the faster prototypes include 3D printing, SLA, and Vacuum Casting. This method can be more profitable for the mass production of large quantities. However, it should not be used for less than 100 parts per unit. Even in the context of small series production, plastic injection will require specific expertise. This is why it is very important that the project is handled by a reliable partner.
