BLOW MOLD ENGINEERING
Blow Mold Design Services
We design parting, pinch-off, neck, venting and cooling structures for blow-molded products and deliver manufacturing-ready design data.
Blow mold engineering scope
- Parting line and opening direction
- Pinch-off geometry and flash area
- Neck and insert structure
- Venting features
- Cooling circuit
- Cavity geometry and machining considerations
- Ejection and post-processing conditions
Product geometry and molding risk
Blow-molded parts can be sensitive to section changes, corners, neck features and pinch-off conditions. Product geometry is reviewed together with mold structure and forming risk.
Wall distribution
Review abrupt geometry changes and corners that can cause uneven material distribution.
Pinch-off
Review joint strength and flash removal requirements.
Neck structure
Review neck accuracy, inserts and local tooling details.
Cooling & venting
Design heat removal and air escape paths for stable molding.
Workflow
STEP 01
Input review
Review product data, resin, process, production volume and quality requirements.
STEP 02
DFM review
Check parting, pinch-off, neck and geometry risks.
STEP 03
Mold design
Develop cavity, parting, cooling, venting and component structure.
STEP 04
Drawing output
Prepare 3D/2D manufacturing data.
STEP 05
Partner support
Coordinate mold manufacturing, trial molding or production when required.
Frequently Asked Questions
Can you support extrusion blow mold projects?
We first review the product geometry, molding process and tooling requirements to define the appropriate engineering scope.
Can mold manufacturing be coordinated?
Yes. After design, specialist mold manufacturing and molding partners can be coordinated when required.
