Plastic Desk Dust Bin Mould

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

ZHONGYUE MOULD is a professional Chinese injection mold manufacturer supplying Plastic Desk Dust Bin Moulds / Mini Desktop Trash Can Injection Molds (0.5L–3L capacity, with or without swing lid / press-to-open lid) to global office-supply brands, promotional gift companies, and household product wholesalers. Unlike large rattan-pattern bins, desk dust bins are compact, thin-walled (1.2–2.0mm), smooth or high-gloss finished (SPI A2/B1 or VDI 27 micro-matte), typically molded in PP (MFR 10–20 g/10min) or ABS (glossy version), optionally with antibacterial masterbatch. Our molds commonly use a three-plate mold with pin-point bottom gate (auto-degating) or hidden submarine gate on the inner rim, central baffle + BeCu (beryllium copper) core insert for ultra-short cycle time (8–15s), and precisely machined hinge-ear inserts for the swing lid pivot — delivering flash-free miniature bins with invisible gate vestige on the visible face.

From mini round/square desk waste baskets (body only), matched swing lids / flip-top lids (often 2-cavity), to promotional logo-engraved desktop bins, we provide full DFM review before steel cutting.

Key Mold Engineering Highlights for Desk Dust Bin Molds

Three-Plate Mold with Bottom Pin-Point Gate (or Hidden Sub-Gate) — Center pin-point gives radially balanced fill for round mini bin, auto-degating with controlled vestige; alternative: submarine gate on inner top flange hides mark from visible outer face. Cold runner standard; hot-tip rare due to small shot size.

Fast-Cycle Cooling — Central Baffle + BeCu Core Insert — Ø8–10mm baffle through core + BeCu (beryllium copper) insert at bin bottom radius; ΔT ≤ 2–3℃ inlet–outlet; target cycle 8–15s for 30–80g PP shot.

Swing Lid Hinge-Ear / Pivot Forming — Precision-machined insert or pinned cavity to mold hinge ears/pivot slot; lid often 2-cavity to match body production ratio; confirm lid-body pivot clearance (0.1–0.15mm typical).

Shrinkage Compensation for Mini Geometry — PP ~1.2–1.8%; ABS ~0.4–0.7%; Moldflow/calculation verified on Ø80–150mm & height 100–180mm to control roundness & lid fit.

High-Gloss or Micro-Matte Surface Finish — Cavity SPI A2/B1 high polish (PP glossy) or VDI 27–30 very fine matte (soft-touch look); core satin SPI B1; logo engraving via changeable insert.

Ejection for Deep Mini Bucket — Ejector pins at base rim + optional air-assist eject for tall (≥150mm) 3L version; core vented 0.01–0.015mm to prevent vacuum lock on small Ø core.

Standard Cavity Config — Desk bin body: single cavity (1×1) for best cooling & quality; Swing lid / small lid: 2-cavity or 4-cavity for balanced output.

Our Mold Manufacturing & Validation Process

Project Kick-off & DFM Review — Analyze wall thickness (1.2–2.0mm typ.), draft angle (≥1° for polished surface; +0.5° if micro-matte VDI 27), gate location (bottom-center pin-point vs. rim sub-gate), hinge-ear pivot dimension & lid-body fit clearance; suggest improvements for sink/weld line avoidance on visible face.

Mold Design Approval (3D) — Full assembly with cooling layout (central baffle + BeCu), three-plate runner & degating design (body) or Y-branch (lid), hinge-ear insert definition, vent grooves on core.

Precision Machining — High-speed CNC rough/finish cavity, deep-hole drilling for cooling baffle, cavity/core mirror/satin polish per spec, hinge-ear insert grinding & fitting.

Assembly & T1 Trial — Run on in-house injection machine; check roundness, lid swing smoothness, gate vestige, cooling cycle; supply trial video + sample parts + dimensional check.

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

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

Frequently Asked Questions — Desk Dust Bin Mold

Q: Can you make molds for the bin body, lid, and optionally a small rocker arm?

A: Yes. We quote the mini bin body as single-cavity mold, the lid as 2-cavity or 4-cavity mold to balance production ratio, and mechanical pivots/arms (if any) as separate small multi-cavity molds. Family mold (body+lid) is not recommended.

Q: What material do you recommend for a see-through / clear desktop bin?

A: General-purpose Polystyrene (PS/GPPS) — good clarity, easy flow into thin walls, low cost. For higher impact-resistance clear look, SAN can be used; for colored gloss bins, ABS is common; PP for opaque budget versions.

Q: What surface finish do you offer — no rattan texture, right?

A: Correct — desk bins are typically smooth. We offer SPI B1/B2 satin polish (standard for PS/PP) or SPI A1/A2 high-gloss mirror (for luxury clear/colored ABS). No EDM/VDI texture unless specifically requested.

Q: What do you need for a quotation?

A: 2D drawing (PDF/DWG) + 3D model (STP/IGS/X_T) OR clear product photos with dimension annotations (Ø top/bottom, height, wall thickness, capacity, weight), annual volume, preferred cavity number for lid (2×1 etc.), material type (PS/ABS/PP).
