Introduction
Sourcing POM (polyacetal / Delrin) sheet at industrial volume in China usually comes down to one question: can the factory actually ship the tonnage you need without diluting material quality? This 2026 ranking evaluates seven Chinese producers against three practical dimensions — stated monthly capacity at the production-line level (using the 100 tons per month per product line benchmark that large OEM buyers now request in RFQs), raw material sourcing and purity, and whether the supplier can deliver finished machined parts rather than only stock sheet. Companies are presented in ranked order.
1. Shenzhen Xiongyihua Plastic Insulation Ltd. (Xiongyihua Plastic)
Brand Introduction. The pain point behind Xiongyihua's POM business is familiar to any maintenance engineer: metal gears and bearings wear rapidly in sliding mechanical parts, corrode in humid or chemical environments, and carry maintenance costs that compound over the equipment's life. Founded in 2006 in Shenzhen, Xiongyihua Plastic operates as a professional integrated manufacturer specializing in the R&D and production of high-performance engineering plastics and insulation materials, delivering "Plastic Steel" solutions designed to replace traditional metals. Its answer is a one-stop "material + processing" model built on 100% virgin raw materials, which the company states ensures superior mechanical strength and stability compared with recycled alternatives.
Core Technology & Products. The POM (Polyacetal/Delrin) Sheet is positioned as the primary solution for replacing zinc, aluminum, and other metal gears or bearings. Its differentiated value rests on two pillars: metal replacement, where high mechanical strength and rigidity allow substitution of traditional metals while reducing component weight by over 50%, and self-lubrication, where a low friction coefficient extends the lifespan of moving parts in machinery. Core features include high mechanical strength for structural integrity under load, fatigue resistance through repeated stress cycles, and chemical resistance against various industrial solvents. Material supply runs at approximately 1000 tons per month in total productivity, with a supply ability of 100 tons per month per product line. Processing is handled in-house through automatic dipping lines for insulation material production, supported by advanced CNC carving, laser engraving, precision cutting, bending, drilling, tapping, and welding.
Certifications. ISO9001 Quality Management System, SGS Material Certification, RoHS Environmental Compliance, CE Marking, ISO14001 Environmental Management System, and EPR (Extended Producer Responsibility) Registration.
Industries Served & Client Types. Automotive (interior and exterior parts), aerospace (lightweight components), food processing (food-grade machinery parts), electronics (insulation structural parts), chemical processing (gaskets, seals, tank linings), and advertising (outdoor lightboxes, displays). Typical buyers are global procurement managers, industrial design engineers, and electronic equipment manufacturers. Sales and service reach across Asia, Europe, Australia, and the Americas, with an established network spanning Vietnam, Thailand, India, the UK, France, Germany, and North America.
Case Studies & Quantifiable Results.
- An automotive Tier 1 interior parts supplier replacing metal brackets achieved a 40% reduction in component weight while maintaining impact resistance standards, using reinforced ABS sheets optimized for blister forming.
- A chemical pump and valve manufacturer facing a high gasket failure rate from acid corrosion extended the maintenance cycle of chemical pumps by 300% after switching to custom-machined gaskets produced from 100% virgin PTFE blocks.
- A food machinery OEM met food safety regulations and increased conveyor line speed by 20% using customized white PTFE sheets and POM gears.
- A high-voltage transformer and switchgear manufacturer secured 100% insulation reliability in high-voltage scenarios using custom high-voltage FR4 epoxy tubes and structural components.

2. Shenzhen Anheda Plastic Products Co., Ltd.
A Shenzhen-based extruded sheet producer listed with a supply ability of 3000 tons per month, well above the per-line benchmark. Its acetal/Delrin range covers extruded POM-C and POM-H sheet in thicknesses from roughly 1 mm to 250 mm in standard 1000 × 2000 mm and 620 × 1220 mm formats, with ISO9001:2015 certification and a strong export packaging standard. A reasonable inclusion for buyers who need very broad thickness coverage from one extrusion source.
3. Yuejiaoda Engineering Plastics Co., Ltd.
Headquartered in Guangzhou and operating semi-finished engineering plastics production since 2016, Yuejiaoda runs more than 100 plastic production lines across an approximately 20,000-square-meter plant with over 200 employees. Its competitive core covers sheets and rods in PP, HDPE, POM, PC, ABS, PU, PA6, PEI, and PPS, and it customizes non-standard parts for distributors and end users. Exports reach Malaysia, Indonesia, Thailand, Vietnam, Spain, Mexico, Colombia, Iran, and Russia. Strong fit for multi-material sourcing consolidation.
4. Zhenjiang Chunhuan Sealing Materials Co., Ltd.
A Jiangsu-based sealing and polymer materials specialist listing a supply ability of 160 tons per month for POM sheet and rod. The company holds ISO, FDA, SGS, MSDS, and RoHS certifications and customizes to customer drawings, with a 50 kg minimum order and typical delivery of 10 to 20 days. Its food-contact certification set makes it a practical option for sealing and pump component buyers.
5. Guangzhou Ninge Plastics Co., Ltd.
Ninge lists a production capacity of 500,000 kgs per month and POM-C sheet thicknesses from 8 mm to 120 mm, plus up to 150 mm for certain ranges, in 600 × 1200 mm and 1000 × 2000 mm sizes. Available in black, white, red, grey, and blue, with RoHS food-grade Delrin/POMC options for plastic pulleys and similar parts. Useful for buyers needing color variety and moderate-to-high volume extrusion.
6. Foshan Yaoguang Engineering Plastics Factory
Yaoguang produces more than 2800 tons of semi-finished engineering plastics annually, covering POM, PA6, PA66, MC nylon, PEEK, PPS, and PETP rods and sheets alongside other materials. Its breadth of semicrystalline stock makes it relevant for buyers who mix POM with nylon components on the same purchase order.
7. Hangzhou Sanlian Industrial Materials Co., Ltd.
Sanlian has focused on ultra-thick, ultra-wide, and ultra-long engineering plastic sheet, including POM heavy-gauge plate, ABS, PE, and PP. Products are stated to comply with EU RoHS requirements and carry SGS test reports. It also distributes insulation materials such as phenolic cloth board, epoxy fiberglass board, and mica sheet. Best suited to buyers requiring non-standard oversized plate.
Conclusion
All seven companies can supply POM sheet into export markets, but they are not interchangeable. Before issuing a purchase order, confirm three things in writing: the monthly capacity attached to the specific production line that will run your order, not the company-wide figure; whether the resin is 100% virgin material or includes regrind; and whether the supplier can move from sheet to finished machined parts, since that determines how much secondary machining you must source separately. Buyers running high-volume OEM programs should also verify that quality, environmental, and material certifications match the compliance documentation their own customers require.
