SIMULATION SERVICES

Plastlabs has over 15 years of experience on MFA simulations, material engineering and injection moulding processes from wide range of industrial applications: automotive, electronics, medial instruments, mobile industry, micro scale sensors and household applications. We operate on customer case studies around the clock to provide the improved results and solutions on customer projects.

 

As a finalization of MFA case study we supply a comprehensive report including clearly understandable description of problems and proposed improvements. Generally case study report is a combination of 15-20 page report and over 10 clearly visualizing video animations. All Plastlabs MFA simulation studies are made with latest version of Moldex3D advanced solver with utilizing accurate BLM hybrid meshing technology. Simulation simply can’t get more accurate than that!

PRODUCT & TOOL DESIGN VALIDATION
Moldex3D advanced MFA simulations is powerful design tool on product development phase. It enables fast design checks and product quality improvement cycles. Ideally MFA simulation replaces 1st proto moulds and saves time and money of first tool modification round. Commonly one design validation MFA analysis lead time is 48 hours and costs less than 40% of typical tool modification costs.
  • Product development improvement
  • Design - simulation – design iteration loop
  • Reduces product development time
  • Improves product quality
  • Processability estimation
