ABOUT US

Creativity and Innovation - two key reasons that NETFORM is an industry-leading manufacturer of advanced cold-formed powertrain components.

The requirements for all Tier 1 automotive suppliers are the same - unerring quality and on-time delivery at pricing acceptable to the customer.

So how does NETFORM differentiate itself?

In our case, it is by tying a passion for both product and process development to the ability to listen and understand your challenges.

Working closely with your engineers - as early as possible in programs - we thoroughly review the part/assembly/issue. After identifying key surfaces and features required, we then generate ideas and opportunities for part consolidation, weight reduction, cost savings etc.

So please, feel free to contact us – we would love to help you.

COLD FORMING FLOWFORMING

WHAT IS COLD FORMING?

Cold forming (also called cold forging or coining) is a process where material is transformed into new shapes at room temperature in high-tonnage presses.

Using a combination of a metal preform, special tooling and mechanical presses, unique complex components can be formed.

Where cold heading is typically used to produce bolts/rivets etc, cold forming at NETFORM is used to produce powertrain components such as planetary carriers and splined hubs.

BENEFITS OF COLD FORMING

One of the major benefits of cold forming is work hardening. This strength increase allows the thinning down of equivalent stamping or forging cross sections, saving weight while not impacting strength. Alternatively, for the same packaging constraints, a stronger part can be produced. This work hardening can also allow the elimination of hardening heat treatments. Part surface quality often can be used as-formed.. Cold forming also allows variable part cross-sections. This in turn provides opportunities for part consolidation.

WHAT IS FLOWFORMING?

Flowforming is a cold rotary forming process where a rotating metal preform is formed over a tool by (typically) three rollers.

The rollers deform the preform, forcing it against the tool (also known as a mandrel), axially lengthening and radially thinning the material.

The material will take on the reverse profile of the mandrel, allowing the forming of features such as splines and piston seal surfaces.

BENEFITS OF FLOWFORMING

Flowforming is an extremely effective way of manufacturing net-formed splines, with minimal material wastage.

These splines have uninterrupted grain paths that have higher toughness than typical cut splines, along with zero porosity concerns. The high level of material deformation during the forming process creates significant work hardening. This can allow for elimination of heat treatment on the splines.

With the correct selection of preform, part consolidation and weight reduction are possible.
