Moulding Process

Moulding processes are an important part of our integrated manufacturing services for producing complex and functional components.

We manage all critical production parameters, including material selection, tool design, process conditions, and post-processing requirements. This ensures consistent quality, dimensional accuracy, and cost-efficient production from single prototypes to serial manufacturing.

As a Stepstone, we select the most suitable moulding and production methods based on geometry, material specifications, and functional requirements to deliver the optimal solution for each project.

Injection Moulding
+

Injection molding is a highly efficient manufacturing process used to produce complex plastic components with excellent dimensional accuracy and repeatability. During the process, the selected material is injected into a precision-engineered mold cavity, where it cools and solidifies into the desired shape.

The technology enables the production of intricate geometries, fine details, and consistent part quality that can be difficult to achieve with alternative manufacturing methods. Depending on the application, injection molding can be an economical solution for both prototype development and medium- to high-volume production.

By combining optimized mold design, suitable material selection, and controlled processing parameters, manufacturers can achieve components with specific mechanical, thermal, and aesthetic properties. This makes injection molding a versatile choice for a wide range of industrial and commercial applications.

Overmoulding
+

Overmolding is an innovative multi-stage process where a secondary material is seamlessly molded directly over a rigid base component. Often used to add soft-touch elastomers to hard plastics, this technique instantly elevates a product's ergonomics, grip, and sealing performance.

Instead of manufacturing separate parts and assembling them later, overmolding fuses them into a single, highly functional piece. The materials bond chemically or mechanically during the injection process, resulting in a flawless, permanent connection.

By perfectly integrating multiple functions, overmolding streamlines production and guarantees consistent quality. It is the ideal solution for automotive parts, medical devices, and consumer electronics where both robust durability and user comfort are essential.

Insert Moulding
+

Insert molding is a highly efficient injection molding technique where pre-made parts—such as metal threads or functional components—are placed directly into the mold before the plastic is injected. As the material flows, it seamlessly encapsulates the insert, creating an incredibly strong mechanical bond.

The real advantage of this process is that it combines multiple pieces into a single, ready-to-use component right out of the machine, completely eliminating the need for secondary assembly. It is the ideal solution for projects that demand exceptional structural strength and long-term reliability, particularly in the automotive, electrical, and industrial sectors.

With precise tooling and process control, insert molding consistently delivers complex, durable hybrid parts while significantly cutting down on assembly time and production costs.

Rubber Moulding
+

Rubber molding is a highly versatile manufacturing process engineered to create flexible, exceptionally durable parts with precise geometries. By curing advanced rubber compounds under strictly controlled heat and pressure, the material achieves its ultimate resilience and final shape.

From critical seals and gaskets to heavy-duty vibration dampers, this process delivers components built to withstand the most demanding operating environments. Depending on your project’s specific requirements, we utilize compression, transfer, or injection molding to guarantee optimal results.

By meticulously matching the right rubber compound with optimized tooling, we ensure superior mechanical, thermal, and chemical performance. Whether for rapid prototyping or high-volume serial production, rubber molding provides a reliable, high-quality solution tailored to your industrial needs.

Materials for Moulding

Material selection plays a critical role in moulding projects, directly affecting part performance, durability, surface quality and production efficiency. Stepstone supports moulded part production with a wide range of engineering plastics, elastomers and specialty materials, helping each project match the right material properties with functional, mechanical and application requirements.

The most commonly used materials

+ABS

ABS is a widely used engineering plastic for moulded parts that require good impact resistance, dimensional stability and a clean surface appearance. It is commonly selected for housings, covers, brackets and functional plastic components where strength, processability and cost efficiency need to be balanced.

+PP

PP is a lightweight and chemically resistant thermoplastic suitable for moulded parts exposed to moisture, chemicals or repeated use. Its good flexibility, low density and cost-effective processing make it a practical choice for industrial components, containers, covers and functional plastic parts.

+HDPE

HDPE offers high toughness, chemical resistance and low moisture absorption, making it suitable for durable moulded parts used in demanding environments. It is often preferred for components that require impact resistance, wear resistance and reliable performance in contact with liquids or chemicals.

+PA6

PA6 is an engineering polyamide known for its mechanical strength, wear resistance and good toughness. It is commonly used for moulded technical parts such as gears, bushings, brackets, guides and functional components where durability and load-bearing performance are important.

+POM

POM is a precision engineering plastic known for low friction, high stiffness and excellent dimensional stability. It is commonly used for moulded mechanical parts such as gears, rollers, bushings, clips and sliding components where accuracy, wear resistance and smooth movement are required.

+PC

PC is a high-performance thermoplastic with excellent impact resistance, dimensional stability and transparency options. It is suitable for moulded parts that require strength, heat resistance and a high-quality finish, including protective covers, housings and technical plastic components.

+PEEK

PEEK is a high-performance engineering polymer used for demanding applications that require excellent mechanical strength, chemical resistance and heat resistance. It is suitable for advanced moulded components used in harsh operating conditions where standard plastics may not provide sufficient long-term performance.
