Composite Technology & Engineering Capability
Complete FRP
Engineering Chain
SUDURA integrates material science, tooling engineering, process control, and validation capability to support reliable composite product development from concept to mass production.
Design Starts from Real Operating Conditions
Every FRP product begins with application requirements. SUSDURA evaluates electrical insulation, mechanical load, flame resistance, weatherability, IP protection, dimensional tolerance, chemical resistance, assembly conditions, and lifecycle expectations before defining the material system and manufacturing route.

Designed for Function. Engineered for Production.
A successful SMC/BMC product must balance performance, tooling feasibility, molding behavior, production efficiency, and long-term field reliability. SUSDURA develops product structure, material selection, mold design, and process parameters in parallel to reduce development risk and improve manufacturing consistency.
01 Ribs
Ribs and bosses strengthen and stiffen SMC/BMC parts, but on Class A outer panels they're avoided — they can create sink marks, localized depressions caused by the non-uniform cooling and shrinking of the material. Harmless on non-appearance surfaces, but a serious issue on cosmetically critical parts, depending on geometry and shrinkage rate.
On non-Class A designs, sinks are minimized or eliminated with the right combination of draft angle, radii, and rib thickness.
02 Radii
The recommended radii is 2mm minimum for inside corner radii and 1.5mm minimum for outside corner radii — smooth transitions let material flow and cool evenly.
Mold Engineering Built Around Process Reality.
Mold design directly determines part accuracy, surface quality, cycle stability, insert reliability, and production efficiency. SUSDURA develops tooling based on material flow, curing behavior, temperature balance, venting, insert positioning, ejection, and shrinkage compensation.

Controlled SMC/BMC Molding Parameters.
SUSDURA controls compression molding through material charge layout, mold temperature, closing speed, pressure curve, curing time, venting, insert positioning, and demolding strategy to achieve stable dimensions, surface quality, and mechanical performance.
| Process parameter | Why it matters |
|---|---|
| Mold temperature | Cure stability and surface finish |
| Press pressure | Fiber flow, compaction, and density |
| Charge pattern | Filling balance and weld line control |
| Closing speed | Air release and fiber orientation |
| Curing time | Mechanical strength and cycle efficiency |
| Venting | Porosity and trapped air prevention |
| Insert position | Pull-out strength and assembly reliability |
| Demolding | Surface protection and deformation control |
Precision Molding for Complex Electrical Components.
For small, detailed, and high-volume components, BMC injection and transfer molding provide excellent flowability, dimensional stability, and electrical insulation performance. SUSDURA applies process control to ensure cavity filling, insert bonding, insulation reliability, and batch-to-batch consistency.

Process Knowledge That Prevents Failure.
SUSDURA identifies potential molding and application risks before mass production by analyzing root causes and optimizing material formulation, mold design, process parameters, and quality controls.
| Common risk | Possible cause | Engineering control |
|---|---|---|
| Porosity | Trapped air, moisture, poor venting | Venting design, moisture control, pressure optimization |
| Warpage | Uneven shrinkage, fiber orientation, temperature imbalance | Mold temperature balance, charge pattern, shrinkage control |
| Delamination | Poor curing, weak bonding, contamination | Cure control, surface preparation, material optimization |
| Incomplete Filling | Low flow, poor charge layout, insufficient pressure | Flowability adjustment, charge design, pressure control |
| Cracking | Stress concentration, over-cure, poor structure | Rib design, radius optimization, cure control |
| Weak Insert Pull-Out | Poor insert geometry or bonding | Knurling, undercut, surface treatment, insert positioning |
| Weld Line | Poor flow path or design | Flow path optimization, weld line relocation, material layout |
