It calls for low initial costs: Higher-grade aluminium or lower-grade steel costs less when compared to that of the high-grade steel needed for large production runs. Certainly, high-grade steel can be used to produce thousands/millions of parts, but short-run injection molding is more suitable for low-volume production.

ABS (acrylonitrile butadiene styrene) injection molding is a standard way to make ABS plastic products. ABS is a strong and lightweight thermoplastic polymer that’s easy to work with. The process involves adding molten ABS into a mold cavity and then removing it after it cools. It’s a fast and useful method that’s used to craft ABS products at an affordable cost. It’s a popular go-to for household appliances, tools, and medical devices. It’s used to make Lego bricks, computer keyboard keys, power tool housings, and power outlet fittings, and in the automotive sector, is used for dashboards, seat belt parts, door trim, and bumpers.

Short-run injection molding is used commonly for the production of high-quality goods. A lot of niche industries rely on this production process to create a low amount of products and accessories each year. It can be used in various ways such as:

ABS’s viscosity increases when heated past its plasticizing temperature (unlike most other amorphous plastics), so it needs to be kept at or below that temperature for good results, especially when it comes to molding thin-walled components. Aside from an increase in viscosity, higher temperatures can chemically degrade ABS, if kept well above the plasticizing temperature. The plastic could also warp if it cools unevenly, but this can be prevented by using a mold with evenly spaced cooling channels. It could also shrink unevenly during cooling, creating sunken areas on the surface, if the temperature is too high or the injection pressure isn’t sufficient. Again, these marks (known as sink marks) can be avoided if you use a mold with a high gate pressure.

In the medical industry: In a lot of cases, medical instruments are needed for specialized uses and will require a few hundred parts and accessories to be produced. It is perfect to use the short run molding for low production runs with high product quality.

Usefulness in the military and aerospace industries: The military and the aerospace industries are very similar to the medical industries. Unlike many fast-moving consumer goods (FMCG) industries, these industries do not always require a large volume of parts and products. In this case, they rely on short run molding to produce a limited number of accessories and parts.

Short run plastic injection molding is a production process that is also known as small batch or low-volume injection moulding. This production process requires reduced capital and a shorter time to develop. This molding system is used for the production of simple plastics through high-grade aluminium or low-grade steel injection molds. High-grade steel injection molds are used in large-volume plastic production runs. The short-run plastic injection molding is best suitable for injection molding production that needs less than 10,000 parts to be produced.

Used for producing limited edition cars and vehicles: Short-run injection molding is used extensively in the production of exotic cars. Many exotic cars are built in very few numbers. This is because it costs money and time to put them together. They are produced by using short run injection molding technology. This molding system can be used to ensure high quality as well as bespoke aesthetics.

It can accommodate a wide range of material options: When it comes to resin options, there are no limits to using short-run molding. There are thousands of available resins that you can use for this production process. In addition, you can also apply the resins used for higher volume molding for this production process.

In relation to the actual injection molding process, there’s a high initial investment for the machinery (which is why it’s better suited for high-volume production), and a minimum part quantity is needed to break even on mold costs. In addition, some may find the DFM’s rules a little limiting when it comes to more creative designs. These standards were created to improve part quality and consistency, as well as cover things like wall thickness limits, the location of reinforcing features (like ribs), and the best hole location/size.

The intricacy of the parts you can make is only limited by a set of well-established DFM (design for manufacturing) guidelines that are created specifically for injection molding. It can make multi-featured, complex parts with metal inserts or overmolded soft-grip handholds, and you can easily add a range of colors (think: Lego bricks). This is all without the need for much human intervention, something that keeps labor costs to a minimum and also makes the parts more affordable for customers (obviously the cost and time required increase with the complexity of the part). ABS is easy to shape, recyclable, resistant to chemicals and heat, and has a low melting temperature. It won’t allow dirt to get in, but it doesn’t do too well in UV light and prolonged outdoor exposure. To give it a little more power against the elements, it can be painted or electroplated with metal.

Produce goods of high quality: People often think that short run molding cuts corners and does not offer accurate dimensional tolerances as well as quality. However, the fact behind this production process is that it offers very high dimensional tolerances. It also provides excellent surface quality while also supporting high-volume injection molding processes. It offers exceptional quality when it comes to fitting different parts together.

We usually run into injection molded products in different stores at all times. Such products are often from big companies that make a high number of these products every year. Every year, they make use of injection mold technology to create a large volume of products. In some cases, they make millions of these products every year to be distributed across the world. This shows that this production model is suitable for large production runs. But what if you want to produce a new product in a few thousand or less? What if you want a low-volume on-demand production process that requires less time and costs? All of these objectives are possible when you use “short run plastic injection molding”. For many people, this is a relatively new process that comes with its advantages.

Production of trial parts and prototypes: There are certain cases where you need more product samples and you can’t just fully rely on the 3D printing machine. When this is the case, you can rely on short run molding to produce more samples for you in less time. This is a lot better than using 3D machines for prototyping which can be greatly limited.

ABS injection molding is a common manufacturing process that involves injecting molten plastic into a mold cavity under high pressure and temperature. This technique is used in the automotive, consumer products, and construction industries for producing various components and products. We’ll cover the definition, uses, process, and techniques involved with ABS injection molding below, but for a brief recap, take a look at our short video below:

Almost any thermoplastic can work for injection molding. They can be filled with reinforcing additives like glass or carbon fiber fillers. You can also inject metals if it’s combined with a plastic filler, allowing the metal powder to flow through the mold. That said, additional sintering is needed for metal injection molding. The ABS injection molding process is the same as with most other thermoplastics. Resin pellets get fed into a hopper, where they’re melted and injected into a mold using high pressure. Once it’s cooled and re-solidified, it’s removed from the mold. The simple and efficient process makes it perfect for high-volume production, and it creates very little waste, too.Â

Does not need any minimum order requirements: High-grade steel molds are used for larger production runs. However, if you are looking to produce several hundreds of certain materials, you don’t have to pay for a minimum amount of products. Simply use the short run injection molding process to mold as many products as you want. In this production system, you are not restricted by any volume requirements.

There are many short run injection molding companies around. However, you need to choose the best option. A reliable injection molding company will offer you all the benefits of this type of molding as we have highlighted above. Many such companies have a great deal of expertise in short-run projects. Additionally, these companies may offer similar production solutions with the use of 3D and CNC machines. This is because all these machines can be used for supporting or complementary services during an injection molding project. This is necessary because, in reality, many of these production systems are used to support each other. Then again, they are more suitable for specific projects that may not require the use of any other production technology. A reliable manufacturing company will provide the best short-run injection molding services. They will also help their customers solve the different problems as seen in short run injection molding systems. It is common to use a manufacturer that has completed thousands of injection molding projects for different customers.

It helps to reduce the overall production time: Short-run injection molding helps increase the turnaround time of parts production by a matter of weeks or days. This usually depends on how complex the mold designs are. This is highly beneficial in comparison to high-grade steel molds which usually take months for production to be completed.
