Structural Process & Bonding Configurations for Overmolding OM 1040X
With its highly shear-thinning melt viscosity and polar chemistry, Versaflex OM 1040X-1 bonds permanently:
| Categoría de Proceso de Moldeo | Compatibilidad de Proceso y Detalles Operativos |
|---|---|
| Biocompatible Medical Device Grips | Excellent. Runs inside our certified ISO Class 7/8 cleanrooms using high-purity translucent pellets to overmold medical syringe barrels, surgical tools, and dental instruments. |
| Low-Viscosity Gaskets & Seals | Excellent. With its low compression set (22% at 23°C), it is ideal for thin-walled diagnostic cartridge seals and medical ventilator gaskets. |
| Dynamic Electronics Overmolding | Good. Allows overmolding onto rigid PC or PC/ABS shells of handheld consumer electronics and medical displays, providing protective shock-absorbing bumpers. |
TPE-Avient GLS Versaflex OM 1040X Tooling & Peeling Prevention Guide
Molding an amorphous overmolding elastomer like Versaflex OM 1040X-1 requires strict thermal interface controls and precise parting line tolerances to prevent peeling:
Perfect Interfacial Adhesion (Eliminating Peeling)
Because OM 1040X-1 relies on chemical compatibility for thermal bonding, we avoid using PVC-based color carriers or dynamic mold release sprays on tool faces. Color concentrates must use EVA, PP, or LDPE carriers. Purging the barrel with low-flow PE or PP before runs is strictly required to protect adhesive purity.
Control de temperatura del molde en frío
We maintain mold temperatures at 20°C–35°C (68°F to 95°F) using pressurized water chillers. Keeping tools cold is critical to freeze the soft elastomeric phase quickly, allowing for automatic, warp-free ejection. Melt temperatures are controlled at 190°C–210°C (374°F–410°F).
Micron-Level Flash Control (S136 Steel Cavities)
Due to the low viscosity of OM 1040X-1 under shear, the molten resin can flash easily. We construct cavities using premium S136 stainless steel hardened to 48–52 HRC and machined on our 5-axis CNCs. This ensures parting line clearances are kept strictly within 0.010mm to avoid flash.
High Isotropic Shrinkage Compensation
Versaflex OM 1040X-1 exhibits high shrinkage (typically 2.00% to 2.60%). Our tooling engineers conduct Moldflow analysis during DFM to balance gate designs, ensuring uniform material compaction to eliminate sink marks near thick-walled grips.
Key Application Fields for TPE-Avient GLS Versaflex OM 1040X
- Medical Device overmolded Consumables (ISO 13485): Biocompatible syringe plunger tips, soft-touch surgical instrument handles, diagnostic device housings, fluid-delivery manifold gaskets, and dental tool grips.
- Handheld Consumer Electronics: Impact-resistant smartphone bumper cases, smart-wearable straps, handheld terminal housings, power tool grips, and protective bezels.
- Industrial Dynamic Sealing: Low-pressure water gaskets, chemical-resistant soft washers, laboratory assay cartridge caps, and protective connector sleeves.
