Technical Parts Blow Molding Solutions
Machine Industry Capabilities for Plastic Technical Parts
Technical blow molded parts are complex, functional components that require precision engineering, mechanical performance, durability, and often integration with other components. Pet All Manufacturing Inc., offers specialized equipment and processes to produce high-quality technical parts in various sizes, geometries, and materials.
Extrusion Blow Molding (EBM) – The Backbone of Technical Part Production
EBM is the most widely used blow molding process for technical parts due to its ability to handle complex, hollow geometries and structural components.
Key Capabilities:
- Complex shapes and large parts (e.g., automotive ducts, tanks, tool casings).
- Multi-layer construction: Incorporates barrier layers (EVOH, PA) or reinforcement layers.
- Handle inserts, threads, over molding: Can mold-in components like clips, valves, or metal threads.
- Wide material support: HDPE, PA, PP, TPU, TPE, PVC, reinforced plastics (glass-filled).
- 3D suction blow molding for intricate parts (e.g., automotive air ducts, HVAC tubes).
- Parison programming for wall thickness control along the part.
Applications: Fuel tanks, air ducts, engine covers, reservoirs, medical device housings, tool bodies, appliance components, construction profiles.
Injection Blow Molding (IBM) – High Precision Small Parts
IBM is used for small technical parts where dimensional precision and surface finish are critical, especially when tight neck tolerances or threads are needed.
Key Capabilities:
- Tight tolerances and uniform wall thickness.
- Ideal for small, functional components (5 mL to ~500 mL).
- No flash or trimming needed – clean parting lines.
- Suited for insert molding and threaded features.
- Compatible with engineering plastics like PP, PETG, PC, and some nylons.
Applications: Medical inhaler chambers, small reservoirs, technical connectors, sensor housings, control knobs, specialty closures.
Injection Stretch Blow Molding (ISBM) – High Clarity & Structural Strength
Though primarily used in packaging, ISBM is suitable for technical parts requiring clarity, pressure resistance, or aesthetic strength, especially in medical, lab, or specialty equipment.
Key Capabilities:
- High precision and visual quality.
- Orientation adds strength — useful for pressurized or load-bearing components.
- Often used with PET or engineering resins for lightweight, tough parts.
- Ideal for medical diagnostic containers, clear enclosures, or pressure-resistant parts.
Applications: Diagnostic fluid chambers, transparent pressure vessels, high-end optical or lab containers.
Material Compatibility for Technical Parts
| Material | Properties | Compatible Tech |
|---|---|---|
| HDPE | Durable, chemical resistant | EBM |
| PA (Nylon) | High strength, heat-resistant | EBM, Suction Blow |
| PP | Lightweight, fatigue-resistant | EBM, IBM |
| PVC | Chemical resistance, flexible | EBM |
| PETG, PC | Clear, impact-resistant | IBM, ISBM |
| TYPE/TPU | Flexible, elastic | EBM, IBM |
| EVOH multilayer | Gas barrier | EBM (multilayer) |
Precision, Automation & Quality Control
- Parison or preform control for wall thickness uniformity.
- Vision systems for defect detection and dimensional verification.
- In-mold trimming and handle insertion.
- Robotic demolding and downstream automation (e.g., punching, welding, QC testing).
- Custom blow molds to accommodate integrated clips, ribs, threads, or sealing surfaces.
Sustainability & Engineering Integration
- Machines can use recycled or regrind materials (especially for non-visible parts).
- Support for lightweighting and design for disassembly.
- Co-extrusion and hybrid molding support structural and barrier needs.
- Integration with CAD/CAM tools, mold flow analysis, and FEA for part development.
