Replacing metals in technical applications? Here's how to do it with thermoplastic compounds

Tackle the challenge of metal replacement confidently with FEM simulation, technical expertise, and LATI's high-performance materials.

Why replace metals: advantages and complexities of technical compounds

In recent years, the need to reduce weight, cut costs, and improve sustainability has driven more and more designers toward metal replacement: substituting metal components with reinforced thermoplastic compounds. However, the transition is not without challenges.
Unlike metals, polymers exhibit complex mechanical, thermal, and rheological behavior influenced by factors like time and temperature. These aspects require a complete rethink during both design and molding phases.

From metal to polymer: the design challenge

Overcoming traditional approaches

Many technical parts are conceived with a “metal mindset,” where isotropic properties and well-established machining techniques simplify the design. Switching to polymers introduces new variables: anisotropy, shrinkage, long-term deformation, creep, and more.
Without the right support, the risk of technical failure in early replacement attempts can discourage even the brightest ideas. Predictive tools and specific know-how are essential for a safe, effective transition.

LATI: Experience, simulation, and co-design since 1995

Complete engineering support

Aware of the complexity involved in metal replacement, LATI established a dedicated co-design technical team as early as 1995. Their mission? Assist customers in project validation through advanced tools and material knowledge.

FEM simulation and real data: the power of forecasting

Using cutting-edge FEM software and material behavior data developed in-house, LATI can:

• Simulate mechanical and thermal stress over time;
• Optimize geometries and adapt material selection;
• Predict shrinkage, warpage, and residual stress during post-molding cooling;
• Significantly reduce financial and time waste.

Designing with polymers? now it’s easier (and less risky)

Cut time and cost, boost performance

LATI’s approach enables a predictive engineering path for metal replacement, avoiding design or tooling errors. This means:

• Faster development cycles;
• Reduced technical risk;
• Quicker go-to-market with lighter, more sustainable products.
