ABS — Acrylonitrile Butadiene Styrene — is a durable amorphous thermoplastic polymer known for its strength, impact resistance, and heat stability. It's made of three monomers:

Keyflex is a leading provider of high-quality plastic injection moulding solutions, offering a range of customised services for a variety of industries. Our team of experts in plastic moulding technology utilise state-of-the-art equipment and technology to ensure that each product is manufactured to the highest standards of quality and performance.

Before you get a high-quality part or final product, a lot of expertise goes into choosing the right ABS material, designing a great mold, and following all the right injection molding procedures. That's why it helps to have experts on your side when creating an ABS injection molding product.

Learning and mastering the critical factors of the injection molding process takes extensive time. Thus, professionals in injection mold building and injection molding can help develop the best process parameters to achieve a reliable and repeatable injection molding process.

Crescent Industries has been helping the medical, defense, and industrial industries create high-quality plastic injection parts for decades. Discover how Crescent Industries can help fulfill your injection molding needs with ABS or almost any commodity or engineered resin grade.

Each of these monomers contributes different attributes to the structure of ABS. Styrene provides a glossy finish in addition to its rigidity. Polybutadiene offers toughness and ductility—similar to malleability. Acrylonitrile makes it resistant to fatigue and chemicals.

At Keyflex, we understand that each project is unique and requires a tailored approach. Our plastic injection moulding solutions are designed to meet the specific needs of our clients, providing them with the flexibility and reliability they need to achieve their goals. Whether you're looking for a one-of-a-kind solution or need to order in bulk, we have the expertise and resources to meet your needs.

When 3D printing first came out, it almost exclusively used ABS. It's still widely used in 3D printing because of its many benefits. These include:

ABS is created by polymerizing acrylonitrile and styrene in the presence of polybutadiene. The ratios of these three components can be varied. Typically, ABS contains at least 50% styrene. However, these ratios vary for different types of ABS to produce different grades. Each of these grades of ABS offers a unique set of properties tailored for specific applications, which include:

As discussed above, ABS plastic comes in many different grades. Whether you need high impact resistance, heat resistance, reduced production costs, or advanced mechanical properties, choosing the suitable ABS grade is vital to creating a high-quality product successfully.

All plastic injection moulding items come in a wide range of colour options including most Pantone colours or silver-plating for a chrome look. Like all our products, plastic moulding can be created for a wide range of flexible designs and we can accept IGES, STEP, PARASOLID and other 3D formats or we can design the part to suit your requirements. When designing a keypad and plastic housing for your product, the ability to have the tooling and production of both parts done in one production plant eliminates problems created when one part does not fit correctly with the other, as the parts are carefully checked together during production, ensuring correct operation in the finished product.

To solidify the ABS in your mold, cooling channels are created in the mold design to ensure uniform cooling of molten ABS. Real-time temperature monitoring also helps ensure optimal conditions are consistently maintained throughout the cooling process. This is done to prevent defects and inconsistencies.

Once cooling is complete, ejection pins help to release the part from the mold smoothly. Post-ejection, each component undergoes a rigorous visual and dimensional inspection, ensuring adherence to specified tolerances and quality standards. Any excess material is trimmed, and additional finishing processes are applied as needed.

Keyflex manufactures parts and tooling for a wide range of thermoplastic materials such as Polycarbonate, ABS, Polyester and blends. Our expertise means that we are able to advise which material is best suited to your requirements. Over-moulding with TPR gives a rubber feel and impact resistance while our high quality precision parts also have a tight tolerance.

Understanding ABS properties is fundamental in the mold design process. The behavior of ABS under various conditions, including its reaction to heat, pressure, and cooling, plays a pivotal role in designing molds. Here are a few things to consider in the mold design process:

There are various considerations when melting and injecting ABS plastic into a mold. For instance, the melt temperature varies between 170 and 320 °C based on the ABS and mold temperature. The injection molding pressure also varies from 700 to 21800 psi. These are specific factors that your plastic injection molding professional will be familiar with when designing your mold.

The types of plastic used to create components and products depend on its strength, heat resistance, flexibility, and other factors. ABS plastic is a versatile thermoplastic with various characteristics that make it ideal for many industries. That's why ABS is used for injection molding to create a wide range of products, from medical devices to industrial products.

The ABS injection molding process is a precise procedure that ensures consistent quality creation of parts and products. This involves paying close attention to injection pressure and temperature controls to guarantee optimal conditions for producing items with all the above-listed attributes and benefits.

One of the key components of our plastic injection moulding process is our commitment to exceptional tooling. Our in-house tooling capabilities include the design, manufacturing, and maintenance of moulds, ensuring that each product is made to precise specifications. Our tooling is designed to be durable and efficient, reducing production time and improving the overall quality of each product.

ABS plastic is hygroscopic, which means it can absorb moisture from the air. Excess moisture in ABS can lead to various issues during the molding process, including surface defects and reduced mechanical properties. To mitigate these issues, ABS is usually dried using industrial-grade dryers. The material is subjected to a specific temperature for a pre-determined amount of time to effectively reduce its moisture content without damaging its intrinsic properties.
