2-Shot molding / 2K molding

2-Shot molding is an innovative manufacturing process used to produce complicated molded parts in multiple materials, and can be used for a variety of product designs across all industries.

2-Shot moulding optimises the co-polymerisation of hard (or soft) plastics and thermoplastic elastomers (TPE’s).

A 2-Shot mould is designed with a top and bottom cavity. During the moulding process the 1st material is injected into the top cavity and the mould opens and rotates. The 1st material is injected into the top cavity again, while the 2nd material is injected into the bottom cavity simultaneously. The mould then opens and the parts are ejected from the bottom cavity; the mould rotates again and then whole process is repeated.

Two-shot molding, also known as two-component molding or 2K molding, is a specialized injection molding process used to produce complex parts with two different materials or colors in a single operation. Here are some common applications of 2-shot molding:
Automotive Components: Two-shot molding is widely used in the automotive industry for producing various interior and exterior components.
Examples include:

Interior trim components with soft-touch grips or inserts for improved ergonomics and aesthetics.
Multi-color or multi-material instrument panels, door panels, and center consoles.
Overmolded buttons, knobs, and switches with different colors or materials for improved functionality and appearance.
Exterior trim parts such as mirror housings, door handles, and grille inserts with integrated seals or accents.
Consumer Electronics: Two-shot molding is utilized in the consumer electronics industry for manufacturing durable and visually appealing products. Applications include:
- Multi-color or multi-material cases, housings, and bezels for smartphones, tablets, laptops, and wearable devices.
- Overmolded buttons, keypads, and grips with soft-touch materials for enhanced user experience and brand differentiation.
- Waterproof or shock-resistant enclosures with integrated seals or gaskets for electronic devices used in harsh environments.
Medical Devices: Two-shot molding is employed in the medical device industry to produce components with biocompatible materials and complex designs. Examples include:
- Multi-material handles, grips, and housings for surgical instruments and handheld medical devices.
- Overmolded seals, gaskets, and connectors for medical devices requiring fluid or gas containment.
- Drug delivery devices with soft-touch or elastomeric components for patient comfort and ease of use.
Consumer Products: Two-shot molding finds applications in various consumer products for improved functionality, aesthetics, and ergonomics. Examples include:
- Multi-color or multi-material handles, grips, and housings for power tools, kitchen appliances, and household goods.
- Overmolded grips, inserts, and seals for sporting goods, recreational equipment, and outdoor gear.
- Personal care products such as razors, toothbrushes, and grooming tools with soft-touch or textured surfaces for enhanced grip and comfort.
Industrial Components: Two-shot molding is utilized in the manufacturing of industrial components requiring durability, chemical resistance, and complex geometries. Examples include:
- Multi-material seals, gaskets, and O-rings for fluid and gas handling equipment.
- Overmolded handles, grips, and ergonomic features for hand tools, machinery, and equipment.
- Electrical connectors, switches, and housings with integrated seals or insulation for industrial applications.

Overall, two-shot molding offers versatility and flexibility in producing parts with unique designs, improved functionality, and enhanced aesthetics across various industries and applications.
