Name Description
Rapid tooling We can also help you in creating Production tooling for Injection Molding, at the same time, with same-day or next-day delivery.
Production tooling We offer high-volume production tooling or export tooling for various industries including Medical, Automotive, and Electronics.
Single cavity molds Single cavity molds are the simplest kind of molds to make. The mold is made with a rubber vulcanizing (RTV) silicone compound and machined with low-pressure injection.
Molds with side-action cores Molds with side-action cores are engineered to facilitate the process of fiber plug removal, a necessary step in extracting finished parts from the mold. This process is particularly crucial in applications where it may be difficult to reach deep inside of the mold cavity.
Multi-cavity molds Multi-cavity molds are specially designed for the mass production of the same part from different materials in a minimum amount of time.
Family Molds Family molds are specially designed for automatic or continuous molding of the same material, where the same materials are used over and over again. This type of mold is typically made of light-weight aluminium.
Insert molding Insert Molding is a simple case of injection molding, where an insert is placed within a mold and then the material is injected into the mold cavity. The insert will be made of a tougher material to prevent wear and tear.
Overmolding Overmolding is a plastic process where the product is injected into a mold that has been filled with another material. For instance, injection of one material into a silicone or rubber sponge. This type of molding is also called two-shot molding.

Available materials for plastic injection molding

At 3DC hub, we work on a wide range of materials for injection molding applications. We are aware of the fact that not all materials are completely compatible with each other. We deliver molded products with different varieties of materials and guaranteed repeatability.


Acrylonitrile butadiene styrene is a common thermoplastic polymer used in the industry for many applications. This material offers a high level of stiffness, impact strength, and toughness in addition to low moisture absorption.


Polyamide-6 is a strong and lightweight polymer widely used in injection molding, plastic bagging, and films. This material is highly resistant to chemicals, weather, and strain.


This material is a combination of polycarbonate and ABS. It is ideal for making products that need to withstand the presence of chemicals and heat.

Polyurethane (PU)

Polyurethane is a durable thermoplastic polymer that provides good impact strength, flexibility, heat resistance, and high-temperature performance.

Acrylic (PMMA)

Polymethyl methacrylate (PMMA) is a strong copolymer used in the manufacture of injection molding products. This material offers excellent optical properties and is highly resistant to scratches, chemicals, and moisture.

Polypropylene (PP)

This thermoplastic polymer has high impact strength, toughness, low moisture absorption, good electrical insulation, and heat resistance.

Polycarbonate (PC)

This material is used for producing high-performance parts and products. It has high chemical resistance, impact strength, and stiffness along with a low moisture absorption rate.

Polyvinyl chloride (PVC)

PVC offers excellent impact strength, chemical resistance, dimensional stability, and solvent resistance.

POM (Acetal/Delrin)

Acetal is a material used for the production of molded products. It is a solid thermoplastic polymer that has low moisture absorption and good dimensional stability along with an excellent surface finish.

Additives and fibers

At 3DC hub, we help our clients in the selection of additives and fibers based on their requirements. We have a vast range of additives that are available in pellets, granules, and bulk forms. Our range of fibers is also very attractive, and it includes:

Name Description
UV absorbers These are used for the protection against ultraviolet radiation. UV absorbers are colorless or translucent in nature and offer high resistance to light.
Flame retardants These are used for the treatment of plastics and other materials to resist the effects of flame. The flame retardants used in the industry are made from halogen-free ingredients.
Plasticizers Plasticizers help in increasing the plasticity of polymers. They function as a lubricant and also improve the flowability of plastics.
Colorants The colorants in the industry are used to impart color to polymers. These products help in making a product easily recognizable.
Carbon fibers Carbon fiber is a strong, light, and lightweight material. The advantages of carbon fibers are excellent tensile strength, high stiffness, and fatigue resistance.

Injection molding design guidelines

3DC hub makes available injection molding design guidelines for its clients. These guidelines are designed to help the clients in making their injection molding products with ease. We follow the standard guidelines and also offer products that are optimized in terms of plastic consumption.

Feature Recommended Description
rtg Wall thickness Thickness: 1 mm and 3 mm The wall thickness has a significant impact on the amount of material used for making a product. At 3DC hub, we provide strong and light products by using thin wall linings that can easily be made.
rtg Smooth transitions 3 × wall thickness difference Smooth transitions help greatly in reducing the usage of material. The injection molding products are made with no or minimum hooks, drafts, and intersections.
rtg Rounded edges Internal edges: > 0.5 × wall thickness External edges: internal fillet + wall thickness Round edges enable an easy release from the mold. A smooth transition is provided at the point of contact between parts and molds.
rtg Draft angle For parts taller than 50 mm: increase the draft by 1° for every 25 mm For parts with a textured finish: increase the draft by an extra 1°-2° The draft angle is used to reduce the usage of material in thin items. It also helps in reducing surface tensions, and it offers good separation between the part and mold.


At 3DC hub, we make available a sample verification program for our clients. This program is designed to help you in selecting a suitable material. We offer products that are customer-specific and are ready to use. The sample verification program includes the following steps:

  • Phase one - This step involves creating mockups that are verified by you.
  • Phase two - In this phase, we create engineering prototypes based on your design. These prototypes are verified through physical testing to ensure their compliance with customer requirements. The testing is also used to ensure the sample's smoothness and consistency.
  • Phase three - The final step involves verifying the engineering prototypes by creating a product that is ready to be used in production.
