Why Choose Us for Hollow Plastic Components?
Hollow geometries demand strict control over thermal behavior, polymer shrinkage, and tool dynamics. We help your team minimize tooling overhead while securing reliable product performance.
Rotational Molding
Best suited for large, heavy-duty hollow structures requiring high impact strength and low internal stress, without the high upfront tooling costs of conventional injection molding.
- • Applications: Tanks, containers, housings, bins, covers, and recreational bodies.
- • Advantages: Seamless corners, uniform wall thickness, and low-cost tooling.
Blow Molding
Engineered for high-volume, thin-walled hollow configurations. Our tooling specialists help determine process feasibility based on part geometry, material flow, and target cycle times.
- • Suitability: Lightweight fluid handling components, ducts, and vessels.
- • Advantages: Fast production cycles and high piece-to-piece repeatability.
DFM Engineering Support
We review your 3D CAD models prior to tool cutting, identifying potential issues with draft angles, wall distribution, parting lines, and material shrinkage.
- • Wall Integrity: Eliminating weak spots across complex contours.
- • Insert Placement: Threaded inserts molded in-situ to cut assembly steps.
- • Resin Selection: Matching LLDPE, HDPE, or Nylon to chemical and load demands.
