TPE plastic mold

We specialize in custom TPE plastic mold development, TPE (Thermoplastic Elastomer) component production, and optional assembly services—not finished product trading. Our molds are engineered to maximize TPE’s unique advantages (soft tactile feel, high elasticity, recyclability) while addressing its molding challenges (e.g., mold adhesion, low rigidity), delivering high-quality TPE parts for consumer electronics, medical devices, baby products, and household goods.

1. Custom Mold Structures: Tailored to TPE’s Molding Characteristics

TPE’s distinct properties (low hardness, high flexibility) require molds that enhance its soft-touch performance and ensure easy demolding. Our custom mold structures include:

Cavity & Core: Machined via high-precision CNC machining (tolerance as tight as ±0.02mm) to suit TPE’s needs:

Textured or smooth surfaces (Ra ≤0.8μm) to replicate TPE’s soft tactile feel—critical for parts like phone cases, baby bottle handles, or remote control grips, where touch comfort directly impacts user experience.

Uniform wall thickness (0.5–3mm) with rounded edges—TPE’s low rigidity makes it prone to deformation in uneven sections; consistent thickness avoids weak points (e.g., tearing at thin edges of grip parts) and ensures uniform elasticity.

Anti-adhesion coatings (e.g., PTFE-based) on cavity surfaces—TPE’s high viscosity and stickiness increase demolding difficulty; coatings reduce friction, enabling scratch-free part removal without damaging TPE’s soft structure.

Gating System: Designed for TPE’s moderate melt viscosity (MFR 1–15 g/10min):

Small-diameter pin gates (0.5–1mm) for small soft parts (e.g., earbud tips, medical seal rings)—enables precise flow control, reducing gate marks that affect tactile feel (critical for parts in direct contact with skin).

Hot runner systems with temperature control (160–200°C) for multi-cavity or two-shot molding (e.g., TPE-overmolded plastic grips)—maintains TPE’s melt stability, cuts material waste by 18–25%, and ensures strong bonding with rigid plastics (e.g., ABS, PP) in overmolding applications.

Cooling System: Calibrated to control TPE’s fast cooling and elasticity retention:

Evenly spaced cooling channels (8–12mm apart) with moderate temperature (40–60°C)—TPE’s fast crystallization requires controlled cooling to preserve elasticity; rapid cooling can make TPE brittle, while slow cooling reduces production efficiency.

Cooling inserts for thickened TPE areas (e.g., grip bulges)—reduces cooling time by 25–35%, avoiding sink marks that ruin tactile comfort and structural integrity.

Ejection System: Suited to TPE’s flexibility and low rigidity:

Wide, flat ejector pins (arranged at non-visible, high-strength areas)—distributes ejection force evenly to avoid stretching or tearing TPE’s soft structure (e.g., thin-walled seal rings).

Stripper plates for large TPE parts (e.g., yoga mat edges, appliance door gaskets)—gently releases parts without deforming their shape, ensuring consistent elasticity and fit.

2. TPE Material Variants & Their Applications

TPE is available in modified grades to match specific tactile and performance needs—we select the right variant based on your component’s function and contact scenario:

TPS (Thermoplastic Styrenic Elastomer): Ideal for consumer soft-touch parts (e.g., phone cases, remote control grips, toy handles). Offers Shore A hardness 30–90 (adjustable for different softness), good elasticity (≥300% elongation), and easy coloring—suitable for indoor, low-stress applications where tactile feel is priority.

TPR (Thermoplastic Rubber): Used for skin-contact parts (e.g., baby bottle nipples, medical gloves, earbud tips). Features hypoallergenic properties (meets FDA standards), excellent skin compatibility, and good oil resistance—safe for prolonged contact with human skin, ideal for baby products and medical devices.

TPU (Thermoplastic Polyurethane): Perfect for durable, high-tensile TPE parts (e.g., sports equipment grips, phone screen protectors, industrial seal rings). Boasts high tensile strength (up to 60 MPa), abrasion resistance, and weather resistance—withstands outdoor exposure and frequent use, suitable for sports and industrial applications.

TPO (Thermoplastic Olefin): Great for low-cost, outdoor TPE parts (e.g., garden tool grips, automotive door seals). Offers good weather resistance (no cracking under UV exposure), low temperature flexibility (down to -40°C), and chemical resistance—ideal for outdoor or harsh-environment applications.

TPV (Thermoplastic Vulcanizate): Suitable for high-temperature or high-stress parts (e.g., automotive under-hood seals, industrial hoses). Combines TPE’s processability with rubber’s heat resistance (up to 150°C) and compression set resistance—maintains elasticity under high temperatures, suitable for automotive and industrial use.

3. TPE Injection Molding Process: Optimized for Performance

Our injection process is fine-tuned to maximize TPE’s softness, elasticity, and production efficiency, with key advantages:

Tactile & Elastic Consistency:

Melt temperature control (160–220°C, grade-dependent)—TPE degrades above 240°C; precise heating ensures optimal flow without material breakdown, preserving softness and elasticity (critical for touch-sensitive parts).

Injection pressure (50–80 MPa) with slow injection speeds—balances TPE’s viscosity to avoid overfilling (which causes flash) or underfilling (which ruins shape), ensuring uniform softness across all parts.

Post-molding elasticity testing (elongation and compression set)—each batch is tested to confirm TPE retains ≥80% elasticity after 10,000 cycles, ensuring long-term performance.

Overmolding Compatibility:

Two-shot molding expertise for TPE-overmolded parts—optimizes temperature and pressure to ensure strong bonding between TPE and rigid plastics (e.g., ABS, PP), eliminating delamination (a common issue in low-quality overmolding).

Customizable bonding strength—adjusts process parameters to meet different application needs (e.g., permanent bonding for phone grips, removable bonding for replaceable seal rings).

Efficiency & Cost-Effectiveness:

Fast cycle times (15–30 seconds per part)—TPE’s fast cooling enables efficient production; for small parts like earbud tips, multi-cavity molds (32–64 cavities) support daily output up to 80,000 components.

Recyclable material utilization—TPE scrap can be reused (up to 20% of raw material), reducing waste and lowering per-unit costs for large orders.

4. Our Services: Beyond Molds—TPE Components & Assembly

We provide end-to-end solutions for TPE production, tailored to soft-touch and elastic needs:

TPE Component Manufacturing: Produce custom TPE parts in sizes (3×3mm to 500×300mm), shapes (grips, seals, tips), and Shore A hardness (30–90). Supports color matching (RAL/Pantone codes) and surface treatments (anti-slip texture, matte finish) to enhance tactile feel.

Value-Added Assembly: Optional assembly services for TPE sub-assemblies—e.g., overmolding TPE onto plastic frames (for grips), bonding TPE seal rings to metal parts (for industrial valves), or assembling TPE-based kits (e.g., baby bottle nipple sets). Delivers ready-to-install sub-assemblies, saving your production time.

Custom Design Support: Offer 3D mold design and TPE prototyping (via injection molding or 3D printing). We produce 20–50 prototype parts in 2–3 days to test TPE’s tactile feel, elasticity, and bonding strength—optimizing the mold design before mass production.
