Why Specialized Plastic Consulting Matters

Most design firms are generalists. Here's why the science of plastics demands specialists.

Litigation-Informed Design

Understanding why plastic parts fail is key to designing, developing, and manufacturing reliable products. Our failure analysis background gives us an advantage in preventing the exact failure modes we've seen in courtrooms.

Polymer Science, Not Just Form

Our plastic experts understand the chemistry and engineering of plastics at the molecular level. We don't just design shapes — we engineer materials, crystallinity, and additive packages for real-world performance.

Decades of Manufacturing Experience

Our team has decades of hands-on experience in the Plastics Industry. We've successfully helped many clients bring their ideas to market rapidly and cost-effectively.

Early Retention Saves Millions

Experienced plastic experts have seen it all and know the pitfalls. Early retention of a highly experienced plastic engineer speeds up the development process and reduces cost — we helped one client save millions through optimized die design alone.

Engineering & Design Services

Five core capabilities — from simulation to production-floor optimization.

Finite Element Analysis & Dynamic Simulation

When designing parts, directional changes must be carefully radiused to spread stresses evenly. Our mold fill & pack analysis optimizes gate location and sizing. Our experienced experts can spot potential design flaws that computer models occasionally get wrong. Our dynamic FEA equipment, powered by high-speed supercomputers, predicts fatigue performance and service life.

  • Static and dynamic FEA stress analysis

  • Fatigue life prediction via supercomputer simulation

  • Mold fill & pack analysis with gate optimization

  • Identification of stress concentrations at radii and transitions

  • Cyclic fatigue testing correlation with simulation results

Material Selection & Chemical Compatibility

The most common cause of plastic product failure is Environmental Stress Cracking (ESC). Material datasheets list strength, thermal, and flow properties but often lack chemical resistance details. We routinely conduct ASTM D543 'Resistance of a Plastic to a Chemical' tests to confirm products won't fail from chemical exposure. There are literally thousands of materials available — choosing the right one requires polymer science expertise.

  • ASTM D543 chemical resistance testing

  • ESC risk assessment for amorphous plastics

  • Carbon fiber & glass fiber reinforcement optimization

  • Cost-performance material trade-off analysis

  • Regulatory-compliant material selection (FDA, UL, ASTM)

Mold Flow Analysis & Mold Design

An example: a plastic toilet flush valve molded from glass-fiber reinforced polypropylene failed in service. SEM images revealed glass fibers oriented parallel to the fracture — weakening rather than reinforcing the material. Our expert predicted improper gate location caused the fiber orientation issue. Mold flow analysis confirmed this: moving the gate would have allowed fibers to orient randomly, strengthening the part.

  • Gate location and sizing optimization

  • Glass fiber orientation prediction and correction

  • Weld line and knit line identification

  • Fill pattern and pack pressure optimization

  • Certified Autodesk Moldflow & Solidworks analysis

Reverse Engineering & Deformulation

Reverse engineering of a plastic product goes beyond 3D scanning. It includes deformulation — identifying the plastic and all additives in the material — and CT scanning to generate a 3D computer model of the part design. This molecular-level analysis reveals exactly what a competitor is using and how their part is constructed.

  • CT scanning for 3D part geometry capture

  • Plastic deformulation (base resin + additives identification)

  • FTIR & GC-MS chemical fingerprinting

  • Competitor material and design benchmarking

  • Intellectual property investigation support

Manufacturing Process Consulting & Scientific Molding

Molding a part involves optimization of the molding process through 'Scientific Molding.' We are experts in implementing this process to improve part quality. Production processes are often not optimized and can easily be adjusted to increase production rate without affecting part performance — reducing cost through both higher throughput and appropriate material selection.

  • Scientific Molding implementation and training

  • Process parameter optimization for quality and speed

  • Residual stress measurement and reduction

  • Cost reduction through material and cycle time optimization

  • Quality control system development for shop floor testing

Failure Modes That Require Better Design

Learning from how plastics fail to design products that don't.

Advanced Capabilities

High-end tools and proprietary methods that set us apart from general design firms.

peg_icon_6
Quality Control System Development

Residual stress in plastic parts is often a key factor causing failure. The fabrication process should be carefully optimized to minimize residual stresses. We develop simple, effective tests for accepting or rejecting parts — like oven-based dimensional change measurements — to detect residual stress before parts leave the factory.

peg_icon_7
Cost Reduction Consulting

Cost is directly related to resin cost and production rate. Some products are over-engineered with expensive plastics when a lower-cost alternative works equally well.

peg_icon_8
Dynamic FEA & Supercomputing

Our dynamic computer simulation expert uses high-speed supercomputers to predict the fatigue performance and service life of plastic parts. Very few design firms have this capability.
