Product Description

Automotive Dashboard Mould – Custom Car Instrument Panel (IP) & Dashboard Injection Mold Manufacturer

ZHONGYUE MOULD is an experienced Chinese injection mold manufacturer supplying Automotive Dashboard Moulds / Plastic Car Instrument Panel (IP) Injection Molds — also called Dashboard Skeleton Molds to global Tier-1 auto parts suppliers and OEMs. Modern hard-panel dashboards are injection-molded in PP+EPDM-Talc (Mineral-Filled Polypropylene, e.g. PP-T20/T30) or PC+ABS for decorative upper skins, with the large skeleton integrating glove box mounts, air-vent recesses, passenger airbag pre-cut zone, and center console docking features. Our molds feature sequential valve gate (SVG) hot runner systems (6–12 drops) to eliminate weld lines on the A-surface, multiple hydraulic lifters/angled slides for deep undercuts and airbag doors, nitrogen-spring-assisted ejection, and分区 cooling for warp control on 1.5–2.0m span panels.

From passenger car IP skeletons, SUV full-width dashboard substrates, to decorative soft-touch / piano-black upper trims, we provide full DFM review and Moldflow simulation before steel cutting.

Key Mold Engineering Highlights for Dashboard (IP) Molds

Sequential Valve Gate (SVG) Hot Runner — YUDO / SYNVENTIVE / Mold-Master — 6–12 drops staged open/close to push weld lines to non-visible flange/back face; critical for class-B interior grain appearance.

Multiple Hydraulic Lifters & Angled Slides — 4–8+ lifters for glove box recess, air-vent pocket, defrost duct dock; hydraulic mini-slides for side-mounted features; nitrogen springs (vs. coil) used on large lifters to prevent fatigue failure.

Passenger Airbag Door Pre-Score / Tear-Seam Design — Molded-in tear line via precision-machined insert or parting-line step; carefully controlled sharp-radius insert to ensure predictable deployment without loose scrap.

Shrinkage Compensation for PP-Talc & PC+ABS — PP-T20 shrinkage ~0.8–1.3%(MD)/1.0–1.5%(TD); PC+ABS ~0.5–0.7%; Moldflow-verified cavity sizing especially on wide-span panels to control warp & gap to windshield/A-pillar.

Matte Grain + Optional Piano-Black Zone in One Mold — Cavity VDI 27–36 leather/matte grain (Mold-Tech / YS) directly etched on 718H/2738HH; S136 (HRC 48–52) mirror-polish insert for high-gloss decorative strip zone.

Deep & Zoned Cooling for Warp Control — Baffle Ø10–12mm + bubbler + BeCu inserts near thick mounting bosses; isolated water circuits (ΔT ≤ 3–4℃) across left/center/right zones to minimize camber on large panel.

Hidden Submarine Gate on Back Face / Inner Rib — Gate vestige completely hidden from A-surface; cold runner rare except for proto — hot drop preferred.

Typical Technical Specifications (Customizable)

Our Mold Manufacturing & Validation Process

Project Kick-off & DFM Review — Analyze wall thickness (2.5–3.5mm typ.), draft angle per grain (≥1.5° for VDI 30+), lifter stroke interference, airbag tear-seam feasibility, gate & ejection; suggest improvements for sink/weld line avoidance on A-surface.

Mold Flow Simulation (Moldflow) — Fill pattern, weld line position (pushed to back/flange), clamp force, cooling uniformity & predicted warp magnitude for wide PP-Talc panel.

3D Mold Design Approval — Full assembly with cooling layout (zoned circuits), SVG hot runner balancing, 4–8+ lifter/slide detail with interference animation, airbag insert definition, texture zone.

Precision Machining — Large-format high-speed CNC rough/finish, deep-hole drilling for cooling, Sodick/Charmilles EDM for fine lifter slots & tear-seam insert, S136 mirror polish & VDI texture etching.

T1 Trial & Correction — Run on in-house large-tonnage machine; supply trial video + CMM dimensional report + sample part for approval; check airbag seam & glove-box fit.

Final Packaging & Shipment — Fumigation-free heavy-duty case, mold operation manual, spare parts list (lifter springs, ejector pins, seals), heat treatment & steel certs.

Frequently Asked Questions

Q: Do you mold the soft PVC/TPO slush skin or just the PP skeleton?

A: We manufacture the injection mold for the PP/PC+ABS skeleton/substrate. Soft slush-skin (PVC/TPO) is typically formed in a separate slush-molding or vacuum-forming process and laminated or assembled onto the skeleton — not injected in this mold.

Q: How do you handle the passenger airbag tear seam?

A: We design a precision-machined insert or parting-line step in the cavity to mold a pre-weakened tear line (scored groove) — NOT a post-mold cut. This ensures predictable deployment and a clean hidden seam.

Q: What hot runner system do you recommend for dashboard molds?

A: Sequential valve gate (SVG) hot runner with 6–12 drops (YUDO/SYNVENTIVE/Mold-Master) is strongly recommended — it allows staged filling to push weld lines to the back face/flange, preserving the grain-finished A-surface.

Q: What do you need for a quotation?

A: 3D part model (STP/IGS/X_T), target material (PP-T20/T30 / PC+ABS etc.), annual volume, your injection machine platen & tie-bar data, surface texture spec & airbag tear-seam requirement if applicable.
