Flip-Top Wheeled Plastic Garbage Bin Mold

1. What types of trash can / garbage bin moulds do you offer (injection, blow, rotational, etc.)?

We offer a variety of moulding technologies depending on the bin design and material:

• • Injection moulding is typical for smaller or medium sized dustbins, pedal bins, bins with flip lids, and bins requiring fine detail or texture.
  • Rotational moulding (rotomolding) is used for large-volume, hollow-body trash bins (e.g. large outdoor wheeled bins) because it yields uniform wall thickness and good structural strength.
  • Blow moulding (less common for bins) might be used for hollow cylindrical bins or certain drum-type structures. For example, some manufacturers provide plastic trash can mould – blow mould (single cavity, HDPE).

The choice depends on size, production volume, wall thickness, mechanical demands, and cost tradeoffs.

2. What is special about the Flip-Top Wheeled Plastic Garbage Bin Mold by Jingnan?

Based on the product description:

• • It is designed specifically for trash cans with mobile wheels and a flip-top (hinged lid) structure.
  • The mould uses high-strength mold steel and 3D CAD design to ensure structural integrity, impact resistance, and fatigue durability (especially at hinge and wheel mounts).
  • The flip-top part has a carefully designed hinge structure to ensure stability over frequent cycling.
  • The wheel-connection mold design emphasizes rotational flexibility and payload capacity; materials may be chosen to be wear-resistant.
  • Gate and cooling systems are optimized by mold flow analysis to ensure even filling, minimize shrinkage and warpage.
  • It is claimed to offer good demolding behavior, smooth product surfaces without burrs, and high precision to facilitate later assembly.

Thus, this mold is intended for clients wanting a ready-to-use solution for wheeled flip-lid trash bins, with performance and quality in mind.

3. What information do we need to provide to get a quotation?

To quote a trash can/dustbin mould, we typically request the following:

• • Product drawings / 2D & 3D CAD models or existing sample(s).
  • Overall dimensions (height, width, depth), wall thickness, and detailed features (hinges, ribs, handles, wheels).
  • Material specification (e.g. PP, HDPE, ABS, etc.).
  • Production volume / estimated shot count (how many units you want to make).
  • Moulding method (injection, rotomolding, blow), runner system (cold or hot), gate location preferences.
  • Mold steel preference (e.g. P20, H13, S136, 718, etc.) and surface finish (textured, mirror polish).
  • Machine parameters (tonnage, clamp size, max injection volume) to ensure mold compatibility.
  • Any special requirements (e.g. inserts, overmolding, undercuts, multi-cavity).

Jingnan, for example, mentions they offer full customization from design to mold testing.

Other industry peers also list similar requirements (see e.g. Kaihua, which supports moulding up to 1,100 L bins, and describes cooling, ejection, etc.).

4. What are the main cost drivers in a trash can mould?

Key cost factors include:

• • Mould size & complexity: Larger molds or those with complex features like hinges, ribs, undercuts, sliding cores, or inserts cost more.
  • Mould steel selection and hardness: Higher grade or corrosion-resistant steel increases cost.
  • Number of cavities: More cavities can increase tooling complexity and cost, though they can reduce unit cost in production.
  • Surface finish & texture: Mirror polish, fine texture or special embossing increases machining time.
  • Cooling & gating system sophistication: More cooling circuits or complex gate layouts raise tooling cost.
  • Trial runs, adjustments, and testing: The cost of iteration (T0, T1, T2) adds to total.
  • Transport, packaging, and export costs: Given the size and weight, shipping the mold (especially overseas) can be significant.
  • After-sales support / spare parts: Shops may include cost for spare cores, spare inserts, or maintenance support.

5. What materials (plastics) are commonly used for trash/dustbin production, and what is their impact on mould design?

Common plastics used are:

• • Polypropylene (PP) – good chemical resistance, moderate stiffness
  • High-Density Polyethylene (HDPE) – good impact resistance, flexibility
  • ABS / PC + additives – for decorative or higher performance bins
  • Blends or modified resins (UV-stabilized, filled or reinforced grades)

Mould design must accommodate:

• • Different melt flow characteristics
  • Thermal expansion / contraction (shrinkage)
  • Temperature constraints
  • Wear on gates or runners (especially with filled materials)
  • Venting (if material off-gases)

Choice of plastic can affect gate size, injection pressure, cooling requirements, and parting line design.
