Passive safety in the automotive sector depends on discrete yet decisive components — parts that must absorb energy, withstand impacts, and maintain structural integrity in critical situations. Zamak, an alloy of zinc with aluminium, magnesium and copper, stands out as a benchmark material thanks to its strength, malleability and dimensional precision.
At Jegan, we analyse the key factors that make zamak an ally in passive safety, the value of a fully controlled injection process from start to finish, and the importance of electrolytic finishes to increase the durability of each component.
The Keys to Zamak in Your Product’s Safety
Zamak’s properties — such as its capacity to absorb impacts and maintain structural integrity — make it ideal for components where safety leaves no room for doubt. Its mechanical strength, malleability and precision in pressure die casting ensure homogeneous, reliable parts that meet extremely tight tolerances — an essential requirement in the automotive industry, where every hundredth of a millimetre counts.
A quality alloy alone is not enough; the production process makes the difference. At Jegan, die casting is carried out under strictly controlled parameters to ensure an internal structure free from porosity. This homogeneity is essential to achieve components with high mechanical reliability, capable of withstanding real-world demands.
How We Control Zamak Injection for Your Safety
Our competitive advantage lies in an integrated manufacturing model. From initial planning to final injection and quality control, the entire process takes place under one roof, ensuring full traceability and reduced response times.
Comprehensive Manufacturing Process Under One Roof
The process includes project preparation and precision mould production — a key step to guarantee repeatability and consistent quality in serial manufacturing. Next, state-of-the-art injection machines transform zamak into components that meet the most demanding technical specifications. This integration enables cost optimisation and maintains confidentiality in critical projects.
The Importance of Quality Control for Every Component
Safety demands verification. Every part undergoes rigorous checks, including:
- Dimensional measurements using high-precision equipment.
- Mechanical strength tests, certifying performance under extreme loads.
- Chemical composition analyses, ensuring the alloy remains within optimal parameters.
This approach ensures that every component leaving Jegan’s facilities is ready to be integrated into vehicles and systems where safety is non-negotiable.
Electrolytic Finishes that Protect and Enhance Your Components
Durability — and, in some cases, aesthetics — are factors that cannot be overlooked in the automotive manufacturing sector. For this reason, Jegan integrates an electrolytic plating process within its facilities, allowing the application of high-quality metallic coatings.
Why Trust Our In-House Electrolytic Plating
By having its own facilities, Jegan maintains full control over key parameters such as coating thickness uniformity, adhesion, and customisation according to each client’s needs. This level of control ensures compliance with both technical and aesthetic requirements — two critical factors in the automotive sector.
Metallic Finishes that Surpass Durability Tests
Nickel, chrome and brass finishes not only provide a flawless visual appearance but also multiply resistance to corrosion and wear. This ensures that components maintain their performance and appearance even under adverse conditions such as humidity, temperature fluctuations or exposure to chemical agents.
