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


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.
