Sol Plastics Engineering Services
At A Glance: When tight deadlines and complex part geometries test your internal bandwidth, Sol Plastics engineering services are here to bridge the gap. Sol Plastics operates as an extension of your team, bringing plastics, resin, and mold-building expertise straight to your project.
Â
Beyond initial product development, Sol Plastics offers Design for Manufacturability (DFM), Moldflow simulation, custom mold fabrication, resin selection, and secondary sub-assembly to streamline production pipelines, shorten cycle times, and minimize scrap rates.
What Engineering Services Does Sol Plastics Provide?
-
Design for Manufacturability (DFM): We review your 3D CAD files to fix wall thickness and draft angle issues before any steel is cut.
-
Moldflow Simulation: We run digital flow tests to catch air traps, warpage, and cooling inefficiencies before production starts.
-
Custom Mold Tooling: We build precision injection molds designed to hold tight tolerances and stand up to high-volume production.
-
Polymer & Resin Selection: We match your performance needs with the right engineered plastics, high-temp resins, or custom blends.
-
Secondary Assembly: We handle insert molding, custom finishing, and work with ultrasonic welding experts to simplify your supply chain.

Sol Plastics provides high-precision engineering and manufacturing solutions. Our partner facilities are optimized for technical efficiency, rigorous quality control, and scalable production to meet complex industrial requirements.
Design for Manufacturability (DFM)
Analyzes 3D CAD models, wall thickness uniformity, rib structures, and draft angles to eliminate tooling defects prior to mold fabrication.
Moldflow Simulation & Thermal Analysis
Models resin flow fronts, cooling rates, air traps, weld lines, and volumetric shrinkage using advanced digital predictive software.
Custom Tooling & Precision Mold Engineering
Designs, fabricates, and maintains high-tolerance injection molds engineered for multi-cavity efficiency and extended production life cycles.
Polymer & Material Selection Guidance
Recommends and formulates commodity polymers, high-performance engineered resins (such as PEEK and Polycarbonate) and custom additive blends.
Robotic Process Automation
Integrates automated end-of-arm tooling (EOAT) and robotic part extraction.
Secondary Operations & Post-Processing Assembly
Insert molding, heat staking, secondary machining, custom packaging, and final sub-assembly.
