Mold for plastic bumpers

We specialize in custom mold development for plastic bumpers, plastic bumper component production, and optional assembly services—not finished product trading. Our molds are engineered to match your plastic bumpers’ unique needs (e.g., impact-resistant structures, complex curved shapes, product-specific fitting) , with tailored designs, material compatibility, and optimized injection molding to deliver durable, protective plastic bumper parts for automotive, electronics, and industrial equipment.

1. Custom Mold Structures: Tailored to Plastic Bumper Requirements

Plastic bumpers (e.g., car bumpers, electronic device edge bumpers, industrial machine collision bumpers) demand high impact resistance, precise fitting with host products, and structural stability—our mold structures are customized to address these key demands:

Cavity & Core: Machined via high-precision 5-axis CNC machining (tolerance as tight as ±0.05mm) to replicate complex details—such as curved protective surfaces (matching product contours), internal (reinforcing ribs, 2–5mm thick for impact dispersion), and mounting grooves (for seamless fitting with product frames). For large bumpers (e.g., car front/rear bumpers), the mold’s split-core design ensures easy demolding while maintaining structural integrity; for small bumpers (e.g., phone edge bumpers), micro-details like anti-slip notches are accurately reproduced.

Gating System: Designed to avoid visible marks on exposed bumper surfaces and ensure uniform material flow. For large bumpers, hot runner systems with multi-point gates (3–6 gates based on size) distribute plastic evenly, reducing internal stress and preventing warping; for small bumpers, submarine gates (hidden at mounting edges) leave no traces, eliminating post-molding trimming. Material waste is reduced by 18–25% via optimized gate placement.

Cooling System: Optimized for bumpers’ irregular, thick-walled structures (3–10mm thickness). Conformal cooling channels (matching the bumper’s curved shape) ensure even heat dissipation—critical for thickened impact zones (e.g., bumper corners) to avoid shrinkage or cracks. For large automotive bumpers, cooling time is reduced by 30–40% via segmented temperature control, boosting production efficiency.

Ejection System: Uses ejector pins (arranged in dense matrices at non-visible areas) or ejector sleeves (for cylindrical bumper ends) to avoid deformation. For flexible bumpers, soft-ejection mechanisms reduce pressure on the material, ensuring the bumper’s impact-resistant properties aren’t compromised; for rigid bumpers, balanced ejection force prevents surface scratches.

2. Suitable Plastic Materials: Matched to Plastic Bumper Applications

Plastic bumpers face frequent impact, environmental exposure (UV rays, moisture, temperature changes), and fitting requirements—we select materials based on protective performance, durability, and use scenarios:

PP+EPDM-T20 (Polypropylene + Ethylene Propylene Diene Monomer, 20% Talc Filled): Ideal for automotive bumpers (e.g., passenger car front/rear bumpers). Combines PP’s rigidity with EPDM’s elasticity—offers excellent impact resistance (no cracking at -30°C to 80°C), UV resistance (prevents fading from sunlight), and lightweight properties (reduces vehicle fuel consumption). The talc filling enhances dimensional stability, ensuring a precise fit with the car body.

TPU (Thermoplastic Polyurethane): Used for small electronic device bumpers (e.g., phone edge bumpers, tablet corner bumpers). Provides high elasticity (Shore A 70–90) for shock absorption—effectively reducing damage from drops—and good wear resistance. It’s transparent or customizable in colors, making it suitable for aesthetic-focused consumer electronics.

ABS+PC Blend: Perfect for industrial equipment bumpers (e.g., forklift collision bumpers, machine edge bumpers). Offers high rigidity (Shore D 80–85) for load-bearing and excellent impact resistance—withstands heavy collisions without breaking. It also has good chemical resistance (to oils and cleaning agents), suitable for factory environments.

PE (Polyethylene): Great for low-cost, lightweight bumpers (e.g., furniture corner bumpers, storage box edge bumpers). Provides good impact resistance, low friction coefficient (avoids scratching other surfaces), and water resistance—suitable for indoor, low-impact scenarios (e.g., home, office).

PA66+Glass Fiber (30% GF): Suitable for heavy-duty industrial bumpers (e.g., construction machinery bumpers). Features high tensile strength (supports high-impact loads) and heat resistance (up to 120°C)—withstands harsh conditions like dust, vibration, and temperature fluctuations.

For custom injection molds, we can provide professional Mold for plastic bumpers services. Usually Mold for plastic bumpers are manufactured using injection molding technology. The mold materials for injection molds can be chosen from P20, 718, S136, H13 and so on. The mold material reflects the mold life and product material requirements.When it comes to customizing blow molding molds, we can provide professional blow molding customization services.

Mold design:

Information you need to provide us

1. If you have drawings, 2D drawings, 3D drawings (preferably in STEP format).

2. If there are no drawings, you need to provide specific length, width, height and weight information. (It’s best to send us samples)

3. Should the mold be sent to your country, or leave the mold in our factory and we will help you produce the product.
