Plastic Desk Dust Bin Lid Mould

Plastic Desk Dust Bin Lid Mould – Custom Mini Desktop Trash Can Lid / Flip & Swing Cover Injection Mold Manufacturer

ZHONGYUE MOULD is a professional Chinese injection mold manufacturer supplying Plastic Desk Dust Bin Lid Moulds / Mini Desktop Trash Can Lid Injection Molds (Flip Lid, Swing Lid, Press-to-Open Lid) to global household products wholesalers, supermarkets, and private-label brands. The lid for a 0.5L–3L desktop dust bin is a small precision part (typically wall 1.2–2.0mm), molded in PP (good hinge properties), ABS (gloss color), or GPPS (transparent peek window), with a smooth high-gloss (SPI A2) or satin (SPI B1) polished cavity — no texture or rattan pattern. Our lid molds are commonly designed as 2-cavity, 4-cavity, or 1+1 L+R mirror cavity to match the slower cycle of the bin body (1×1), with hidden submarine gates, balanced Y-branch runners, and optional precision-machined pivot holes for swing-lid or press-lid mechanisms.

From snap-fit desk bin lids, swing / flip-top lids with integrally molded hinge, to press-open lids with spring-pivot recess, we provide full DFM review before steel cutting to ensure balanced fill, minimal warp, and accurate pivot-hole concentricity.

Key Mold Engineering Highlights for Desk Bin Lid Molds

Multi-Cavity for High-Efficiency Matching (2 / 4 / 1+1 Cavity) — Bin body usually 1×1 (cycle ~12–18s); lid molded 2×2 or 4×1 (cycle ~6–10s) to balance daily output ratio without overproducing lids. Runner Y-branched and balanced per cavity fill time.

High-Gloss / Satin Polish Cavity — No Texture — SPI A2/B1 standard (mirror/satin) on all visible faces; NO VDI or rattan etching — critical for clear PS or gloss ABS lids. Core also polished to aid release from small draft angles (≥1–1.5°).

Hidden Submarine (Latent) Gate on Inner Flange / Back Face — Gate vestige invisible from outer visible face; clean shear break. Cold runner standard for multi-cavity lids; optional hot-tip for single-cavity premium clear PS lid.

Precision Pivot / Hinge Detail — For swing/press lids: small core pins (Ø2–4mm) machined to H7 tolerance for pivot hole concentricity; living hinge zone locally thinned with controlled cooling to preserve flex-fatigue life in PP.

Short Cycle & Easy Ejection — Ejector pins symmetrically placed; part typically shallow-draw → simple stripper or pins suffice; vent 0.01–0.015mm on parting line to prevent burn on thin sections.

Optional Logo / Recycle Symbol Insert — Changeable insert in cavity for brand marking on non-visible inner side or back face.

Our Mold Manufacturing & Validation Process

Project Kick-off & DFM Review — Analyze wall thickness (1.2–2.0mm typ.), lid-to-bin interference fit, hinge thickness (if integral PP hinge), pivot hole position, gate location & runner balance for multi-cavity; suggest cavity number to match body mold output ratio.

Mold Design Approval (3D) — Full assembly with runner Y-branch balancing, cooling layout, precision core-pin definition for pivot holes, venting strategy (0.01–0.015mm).

Precision Machining — High-speed CNC rough/finish cavity, deep-hole drilling for cooling baffle, core/cavity mirror/satin polish per SPI standard, hinge zone fine-finishing.

Assembly & T1 Trial — Run on in-house injection machine; supply trial video + sample parts + dimensional check (pivot hole Ø, lid seating fit on bin body sample).

Correction & Final Approval — Fine-tune if needed; ship in fumigation-free case with mold manual & spare parts list (ejector pins, core pins, sprue puller).

After-sales Support — 1-Year mold warranty, free spare parts for non-man-made damage, remote technical guidance.

Frequently Asked Questions — Desk Bin Lid Mold

Q: Should the lid mold be 2-cavity or 4-cavity? How do I match it with my bin body mold?

A: Bin body is usually 1×1 (cycle ~12–18s). Lid cycles faster (~6–12s), so we typically quote 2-cavity or 4-cavity lid molds to roughly balance daily output. Tell us your planned body cavity count & daily volume — we'll calculate the optimal lid cavity number.

Q: Can you mold an integrally hinged swing lid (living hinge) in PP?

A: Yes. We design the hinge zone with controlled thin-section (0.25–0.4mm), dedicated local cooling, and advise PP grade with good hinge fatigue life (MFR 10–20). Hinge fold-test verified at T1 trial.

Q: What surface finish — any texture?

A: No. Desk bin lids are smooth — SPI B1 (satin) standard, SPI A2 (high gloss) for premium/ABS versions, SPI A1 for clear PS peek-window lids. No VDI/rattan etching.

Q: What do you need for a quotation?

A: 2D drawing (PDF/DWG) + 3D model (STP/IGS/X_T) OR clear photos with dimensions (shape, Ø/top size, wall thickness, hinge type if any); tell us your bin body cavity number (1×1 etc.) and daily volume — we'll propose lid cavity layout. Also specify material (PP/ABS/PS).
