Overmoulding & plastic injection moulding for wiring harnesses

Overmoulding on wiring harnesses

An industrial company specialising in your wiring harnesses

Your wiring harnesses, cables and electronic components are exposed to severe stresses: humidity, vibrations, impacts, extreme temperatures and challenging environments. Under these conditions, reliability, waterproofing and long-term durability become key factors for the performance and longevity of your products.

Overmoulding provides a comprehensive industrial solution to protect, reinforce and secure your products for the long term. As an industrial company, AMPERE Group supports you in implementing plastic injection overmoulding to precisely meet the functional, environmental and regulatory requirements of your sector.

Expertise in low and high pressure overmoulding

Low pressure overmoulding

Low pressure overmoulding is a plastic injection moulding process that uses hot-melt resins as the overmoulding material, enabling sensitive areas to be encapsulated without exerting mechanical stress on the components. This process is particularly well suited to protecting electrical harnesses, wiring, cable assemblies and electronic components, especially when these contain fragile or pre-assembled parts. This technique enables:

protect your electrical harnesses and connection areas
ensure sealing against moisture, dust, and vibrations
secure your cables and relieve strain
meet small- or medium-batch production requirements

For these applications, AMPERE Group designs and manufactures tailored aluminium moulds, offering flexibility, speed of deployment and the ability to adapt to customer requirements.

Low-pressure overmoulding
High-Pressure Overmoulding

High pressure overmoulding

High pressure overmoulding is based on a high-pressure plastic injection moulding process and is designed for applications requiring high mechanical strength and excellent durability. This type of overmoulding is used when the part plays a structural or functional role, particularly in exposed and challenging environments.
The benefits of high pressure overmoulding include:

enhanced mechanical and environmental resistance
the integration of complex shapes and mechanical functions,
precise finishing and high industrial repeatability for mass production

It is used when overmoulding plays a structural or functional role, particularly on connection points subject to high mechanical stress or exposed to challenging environments.
AMPERE Group specialises in the design of steel moulds, enabling the production of several thousand parts that guarantee robustness and long-term durability.

Industrial MEAONS OF PRODUCTION dedicated to overmoulding

The AMPERE Group has industrial meons of production dedicated to overmoulding, with low and high pressure moulding machines located at two production sites: in France and Morocco. We manufacture wiring harnesses for various sectors, including defence land vehicles and air-conditioning and heating systems.

Our teams are experts in selecting and implementing the most suitable overmoulding technique, taking into account the mechanical, environmental and functional constraints of each application. Right from the early stages, we integrate mould design and the definition of overmoulding techniques through co-design with our clients, to ensure reliable and sustainable industrial production.

Thanks to this overmoulding technology, AMPERE Group protects your wiring harnesses and ensures their performance throughout the product’s entire life cycle.
