Your production options for rapid injection molding & low volume plastic parts

Rapid injection molding technology helps companies quickly produce plastic parts in low-cost, high-precision prototypes and in small batches. Rapid injection molding is similar to conventional injection molding, but there are still differences between the two, which also makes the design of the parts suitable for rapid molding slightly different from that of conventional injection molding. want to know more, please go here.

How does rapid injection molding work?

In the first place, granular or powdered plastic is added to the barrel, and the plastic is softened by the revolution of the screw and the warming of the external mass of the barrel. Then the screw advances so that the molten material is injected into the closed mold at a lower temperature at high pressure and faster speed. After a certain period of time and pressure, it is maintained (also called holding pressure), cooled, and solidified. Then you can open the mold to take out the product.

Compared with vacuum casting

1. Vacuum casting

Vacuum casting technology is to use product prototypes (rapid prototyping parts, CNC hands) to make silicone molds in a vacuum state and to pour materials such as PU and ABS under vacuum to clone the same copy as the product prototype.

The cost is low, and the product production cycle is relatively short. Less waste and processing costs are much lower than CNC processing and 3D printing.

If the number of small batches does not exceed 50, the compound mold will be a very good choice and rapid injection will be better as the number increases.

2. Rapid Injection Molding

A low volume model is the most ideal approach to spare time and cost for the testing structure and fit just as a starter showcase test, however at any rate it can't coordinate the last completion and capacity impact of the infusion formed plastic parts. At the point when your creation tooling won't be prepared for quite a long time, fast infusion forming (otherwise called model trim or delicate tooling) at that point is an incredible choice for you to get parts rapidly with less expense. 

Before the creation instruments are prepared, it for the most part takes three to four months. During this period, a few items should be put available for execution testing. So as to infuse a great many test parts, we either needed to make countless RTV silicone shape or pay a significant expense to make hardened steel molds. Whichever way is costly. Fast infusion shaping tackles this issue, creating 1,000 to 10,000 models rapidly and monetarily.

Benefits of low volume injection molding

1. Uses different materials

The manufacturer offers more than 100 different colors of thermoplastic resins and additives. Properties such as durability, strength, chemistry and heat resistance vary from plastic to plastic.

2. Saves costs and time

The manufacturer provides a great option for your injection molding materials, which shorters the delivery time and save costs for your project.

An example of rapid injection molded parts on medical devices is the American company TeleCare in Minnesota, which produces an audio device called inLife that allows patients to test their pulse, weight, blood pressure, and blood sugar levels at home. The system can also record each set of data in the form of a data map, which is then transmitted to the server through the telephone line, and then uploaded to the patient's record, which is convenient for physicians to review. In the process of developing this equipment, the company's problem was that the production speed of the parts was too slow. Finally, they used rapid injection molding.

3. Bridges a gap of quantities, covers a small batch of demands

So as to completely fulfill the need for fast creation and cost decrease, regularly we use the Master Unit Die (MUD) frameworks to rapidly change form bases which are demonstrated to spare tooling time and diminish costs. Considerably more significantly, building changes include just the MUD shape embed, not a whole standard form base. You can likewise bunch a few comparative parts on what is known as a family instrument for more noteworthy investment funds. What's more, manual or self-loader embeds are additionally frequently utilized in quick shape tooling.


With such a tooling approach, we can keep the venture cost low and if there should be an occurrence of any adjustment we could actualize immediately mentioned change.


Need 100, 1,000, 50,000, or 100,000? Or on the other hand more? At the point when you need low-volume creation shaped parts on a short course of events, there are no confinements to what we can deliver.
