Harbermetal expands MIM capacity with unified prototype and mass production line

Harbermetal said it has merged prototype development and mass-production operations at its Dongguan plant, a move aimed at cutting lead times, lowering costs and improving quality control for custom metal injection molding parts. The company also plans to buy two magnesium alloy injection molding machines and showcase the expanded capacity at PM CHINA 2027 in Shanghai.

Why it matters: - Harbermetal says the new one-site workflow removes delays between prototype sampling and mass production. - The change is designed to speed up custom MIM part development, improve batch consistency and reduce project costs for overseas buyers. - The capacity push comes as demand grows for complex miniature metal parts used in automotive hardware, consumer electronics, power tools, security locks and medical auxiliary components.

What happened: - Harbermetal completed the integration of its prototype development division with its main mass-production plant in Dongguan, Guangdong, China. - The unified setup brings prototype testing, mold trial, debinding, sintering and post-processing into one plant. - The company said the consolidation shortens the standard lead time from 35 days to 25 days. - Harbermetal also said the change reduces overall project cost by 6% to 9% for overseas buyers. - On August 16, Harbermetal placed an order with Jielong Import and Export Trading Co., Ltd. for two JSW-brand magnesium alloy injection molding machines. - The purchase price totals 51 million Japanese yen, or about 2.5 million Hong Kong dollars.

The details: - The unified manufacturing base covers feedstock compounding, mold fabrication, metal injection molding, debinding, vacuum sintering, heat treatment, secondary CNC sizing and surface finishing. - The plant now uses newly installed Japanese Shimadzu sintering furnaces within the same production flow. - Harbermetal said the furnaces support both small-batch prototype sintering and large-volume continuous mass sintering. - The company said the expanded workflow improves equipment utilization and overall MIM production capacity. - On-site inspection equipment includes CMM, carbon-sulfur analyzer, metallographic microscope and density test instruments. - Harbermetal said the quality-control system meets MPIF 35, ASTM B883 and GB/T 26726 standards. - Jielong Import and Export Trading will deliver the two magnesium alloy injection molding machines in batches between April and May 2027. - Harbermetal will pay 30% of the purchase price as an advance within two weeks after signing the order. - The remaining 70% is due after delivery and installation. - The machines come with a 12-month warranty, including free maintenance and replacement of defective components during the warranty period. - Harbermetal said it built a new 1,200-square-meter plant in 2023 focused on small, complex, high-precision metal parts. - The company operates two production bases with closed-loop manufacturing lines and in-house R&D and production capabilities. - Harbermetal said it serves commercial kitchenware, consumer electronics and automotive industries. - The company will show its expanded MIM capabilities at PM CHINA 2027 in Shanghai at Booth D47. - Harbermetal said it will display stainless steel, bronze, titanium and nickel alloy MIM parts at the show. - Justin Lee, general manager of Harbermetal, said the integrated workflow keeps the same material formula, sintering recipe and quality inspection standards from first article sample to full production.

Between the lines: - The consolidation points to a broader shift toward tighter process control in precision manufacturing, where separate prototype and production lines can create quality drift and schedule delays. - The new furnace and machine purchases also suggest Harbermetal is betting on both higher throughput and a wider mix of materials, not just one product category. - The move should help the company compete for global buyers that want shorter development cycles and fewer handoffs between sample approval and volume production.

What's next: - Harbermetal plans to receive the two magnesium alloy injection molding machines in 2027. - The company will use PM CHINA 2027 as a venue to pitch its expanded MIM manufacturing capacity to engineers and procurement teams. - Harbermetal is likely to keep emphasizing one-site development and production as a selling point for custom MIM projects.

The bottom line: - Harbermetal is turning its MIM operation into a more integrated factory model, aiming to move faster, cut costs and deliver more consistent precision parts at scale.
