Thin wall bucket molds manufacturer
With over 20 years of deep expertise in bucket mold manufacturing, YUCO Mold leverages state-of-the-art processing equipment, a rigorous quality control system, and extensive industry experience.
- Precision machining accuracy - Equipped with Swiss 5-axis machining centers and German CNC grinding machines, we maintain critical dimensional tolerances within ±0.02mm. This ensures that every cavity produces parts with uniform wall thickness, consistent aesthetics, and stable dimensions.
- High-efficiency hot runner systems - We utilize standard hot runner systems from leading international brands such as YUDO and HUSKY. The valve-gate design ensures balanced filling across multiple cavities, eliminates cold slug waste, minimizes gate marks, and delivers superior product surface quality.
- Flexible multi-cavity configurations - We offer customizable configurations ranging from 1 to 16 cavities. The runners are precisely balanced using Moldflow simulation software, ensuring a weight deviation of less than 0.5% per cavity—perfectly suited for high-volume, mass-production requirements.
- Ultra-short cycle times - Featuring spiral conformal cooling channels paired with beryllium copper inserts, our molds boost cooling efficiency by over 30%.

YUCO thin-wall bucket mold manufacturing process
A Thin-Wall Bucket Mold is a precision injection mold designed to produce thin-walled cylindrical containers, typically with wall thicknesses of 0.6 mm to 1.5 mm. Compared to traditional bucket molds, thin-wall bucket molds impose more stringent requirements on the mold steel, cooling system, gating system, and mold clamping precision.
Every YUCO thin-wall bucket mold undergoes a rigorous, standardized manufacturing process—fully traceable from design through delivery—to ensure consistent, reliable mold quality.
01 DFM analysis and design
Clients provide product drawings; YUCO engineers generate a DFM (Design for Manufacturability) analysis report, optimizing critical parameters such as wall thickness, draft angles, and gate locations.
02 Precision steel machining
The process involves 5-axis CNC roughing → finishing → EDM (Electrical Discharge Machining) → coordinate grinding, with critical areas polished to a mirror finish of Ra ≤ 0.05μm.
03 Heat treatment and surface finishing
The mold cores and cavities undergo vacuum quenching and tempering, followed by surface treatments—such as hard chrome plating or PVD coating—to enhance wear resistance and mold release performance.
04 Assembly and debugging
Following precision assembly, a pre-clamping inspection is conducted to measure the clearance between guide pillars and guide bushings; the hot runner temperature control system is then debugged to ensure smooth and reliable operation.
05 Mold trials and acceptance
T1 and T2 mold trials are performed on in-house injection molding machines. Sample parts and dimensional inspection reports are provided for client review; upon confirmation of acceptance, the mold is packaged and shipped.

Frequently asked questions
What is the fundamental difference between thin-wall bucket molds and standard bucket molds?
The core challenge of thin-wall bucket molds lies in the inherent conflict between extremely thin wall thicknesses (typically ≤ 1.5 mm) and ultra-short molding cycles (typically < 10 seconds). This necessitates that the mold possess a superior capacity to withstand high injection pressures (exceeding 2000 bar), a highly precise cooling system (with cooling times of just 1 to 3 seconds), and exceptional steel hardness and polishing precision.
These requirements ensure smooth demolding and dimensional stability of the finished product, making it one of the most technically demanding types of bucket molds to manufacture.
What materials are used for the molds, and what service life (number of cycles) can be guaranteed?
The standard configuration for YUCO thin-wall bucket molds utilizes S136H pre-hardened mirror-finish steel (HRC 48–52), guaranteeing a mold life of no fewer than 1 million cycles. Our high-end configuration employs imported HPM-38 steel, capable of achieving a service life of 2 to 3 million cycles. The actual service life, however, also depends on the production materials used, maintenance frequency, and injection molding process parameters. We provide a detailed mold maintenance manual to guide our clients on how to extend the service life of their molds.
Can YUCO provide custom solutions based on my product drawings?
Absolutely. YUCO Mold specializes in custom mold manufacturing. Clients simply need to provide 2D product drawings, 3D files (in STEP or IGS format), or physical samples; YUCO engineers will then generate a complimentary DFM analysis report to assess manufacturability and offer optimization recommendations. This is followed by the formal design and quotation process, ensuring efficient and transparent communication throughout the entire project.
What products are suitable for production using thin-wall bucket molds?
Thin-wall bucket molds are widely applicable to: food packaging (ice cream tubs, butter tubs, yogurt cups), paint containers (1L/5L/20L), chemical packaging drums, motor oil containers, pesticide drums, construction sealant cartridges, and more. For any application scenario that requires product lightweighting, involves large-scale production batches, and is sensitive to cost and efficiency, thin-wall bucket molds represent the optimal choice.
Is the hot runner system included in the mold quotation?
Yes, YUCO’s quotations for thin-wall bucket molds typically include the hot runner system (including the temperature control unit). We partner with leading international hot runner brands—such as YUDO, HUSKY, and MOLD-MASTERS—and can also recommend cost-effective domestic brands, such as HYWIN, based on the client’s budget. The choice of hot runner brand does not affect the structural design of the mold and can be flexibly adjusted to meet specific requirements.
