Low-Volume or Short Run Injection Molding Solutions at Abtec

The process of bringing a new product to market involves many steps, including designing the component and creating prototypes to test out the design. After the design is finalized and the prototypes are evaluated, you may also want to produce a small number of pieces for internal or external product testing purposes before proceeding to full production. In the case of injection-molded components, one option for producing these pieces is short run injection molding—also known as small-volume, low-volume, or small-batch production. This production solution enables you to generate a limited batch that you can use to gauge market reaction so you can appropriately scale production to meet actual consumer demand.

Need help with a short-run injection molding project? The injection molding experts at Abtec are here to help! We can assist you at every step of your project, from design to prototyping to production, ensuring you receive the components you need how and when you need them.

Benefits of Short-Run Injection Molding

Short-run injection molding offers numerous benefits. For example:

  • It serves as a bridge between the prototyping and full production stages. Since short-run injection molding produces only a small number of pieces, it allows the production team to push out a product that can still be adjusted later on depending on its performance in the market.
  • It produces high-quality components. Since short-run injection molding accepts automation technology and utilizes low-cost, high-quality materials, it easily outputs superior parts and products at competitive prices.
  • It allows companies to reduce in-house inventory while meeting lead-time demands. Short-run production quickly produces finished components, so they can be sent back to the customer and introduced to the market in a shorter period. As a result, companies can have parts produced and delivered on an as-needed basis.

Plastic Injection Molding for the Medical Industry

At Abtec, Inc., we specialize in custom injection molding, creating tools and parts for customers all over the world from prototype to large production runs. Plastic injection molding is a manufacturing process that involves injecting liquified plastic into a mold, allowing it to conform to the shape of the mold and harden to create a specific shape. This beneficial process has numerous applications in many industries, including the medical industry.

Components and devices for the medical industry must comply with strict industry standards and be made from durable, reliable, and FDA-approved materials. Plastic injection molding not only meets these criteria, but it also offers a host of additional benefits for the medical industry.

The Standards Met & Materials Commonly Used

Parts made for the medical industry must conform to strict standards due to the nature of their use. The FDA outlines different requirements for implantable devices and those being used for medical instruments, and other external use; therefore, it is crucial to consider your application when selecting a medical-grade plastic for the molding process. Other factors such as strength, resistance to heat and chemicals, and operating environment must also be considered when selecting a material to ensure that the part will hold up while in use.

medical grade plasticsCommon medical-grade plastics that can be used with injection molding include:

  • PP. Heat and radiation resistance over extended periods
  • PEEK. Resistant to chemicals and high temperatures, resists fatigue and cracking, works well in radiation-prone environments, and easily sterilized.
  • Polycarbonate. Flexible, high heat resistance, transparent, UV resistance, durable, and resistant to flames.
  • Polysulfone. High temperature with high mechanical strength and rigidity. Good creep strength that is remarkably high over a wide range of temperatures.
  • POM. Resistant to multiple cleaning and disinfection agents, and to a number of solvents. It can be steam sterilized by medical industry’s usual methods, and will maintain good strength, stiffness, and dimensional stability.
  • PEI. Remarkably high creep resistance over a wide temperature and a high permanent operating temperature. Resistance to hydrolysis, along with dimensional stability
  • Polyphenylene Oxide. Strong with outstanding mechanical, thermal and electrical properties. Very low moisture absorption, low thermal expansion, excellent insulating properties, flame resistance, and dimensional stability over a wide range of service temperatures.
  • Polyphenylen Sulfide. A semi crystalline, high temperature thermoplastic polymer. Chemically resistant polymer with amazing mechanical strength, even at temperatures above 200°C (392°F), very stable dimensionally with low susceptibility to creep.

There are many benefits to injection molding for the medical industry, the most prominent being how easily and quickly supplies can be made. Unlike other materials, plastic can be easily injected into a mold to take almost any shape needed, curing into a durable piece of equipment with high levels of precision. This helps to keep prices low, allowing medical facilities to remain sufficiently stocked with important instruments without excessive costs. Cleanliness is also a benefit, as many of these plastics are easy to clean and sterilize without issue.

Abtec Provides Medical Injection Molded Parts

The injection molding process follows these steps:

  1. Create a mold. Injection molding requires a pre-made mold for the material to be injected into. This can be a template for existing pieces or a custom design.
  2. Inject. Pelletized resin which is heated to liquid, is injected into the mold. The plastic fills in the spaces within the mold, forcing out air through tiny vents along the sides.
  3. Cooling. The melted plastic is cooled, allowing it to harden. This is done with a network of water pumps or air vents built throughout the mold that displace the heat from the plastic.
  4. Remove and clean. Once hardened, the part is removed/ejected from the mold and the part is (if necessary) cleaned of any debris or bits of unnecessary plastic.

Abtec, Inc. is at the forefront of medical injection molding and can produce parts or fittings for a large number of applications. We’ve worked closely with our customers to manufacture top-of-the-line moldings and products, including:

Is 3D Printing Better Than Injection Molding?

Advanced technology gives companies more options when it comes to producing plastic components. Plastic injection molding and 3D printing are two of those options, and they both have their advantages, depending upon the application. While 3D printing is relatively new and attention-grabbing, plastic injection molding is still a trusted solution for precision manufacturing.

3d printing vs injection molding3D Printing vs. Plastic Injection Molding

It helps to understand the difference between these processes:

  • 3D Printing: As an additive manufacturing process, layers of material are put together to create the final shape as designed in a digital file.
  • Injection Molding:A proven process for 150 years and counting, injection molding starts with the creation of a mold. The materials are melted, then injected into the mold where it’s left to cool and harden into the finished product.

When determining which process is right for your product, you need to consider the pros and cons of each. 3D printing is great for small production runs and prototyping of small parts or components. Because there’s no mold that has to be created, it’s easy to make changes to the digital design—giving you lots of flexibility when perfecting a new product or when producing something you know you will make changes to on an ongoing basis.

As a newer technology, there are occasional glitches to the process that can interrupt production. 3D printing is also more likely to leave ridges and small defects in the product and 3D printing tolerances are not tight, so you may not end up with precise replicas if you’re creating multiple units.

Plastic injection molding is ideal for larger production runs of all types of components—big or small, simple or complex. After the mold is created, you can work quickly to produce hundreds or thousands of high-quality components with consistent precision. The bigger the run, the lower the cost per unit.

Once built, it can be costly to make changes to the mold.  Which is why it is important to perfect the design before tooling begins.  This is where 3D printing and custom injection molding work well together: 3D printing can be used for experimenting and prototyping, then you can ramp up production with injection molding.

Chances are, you use products every day that are made with 3D printing and injection molding:
