Weiheng

What Weiheng does

Weiheng (常熟市伟恒模具铸造有限公司 / Changshu Weiheng Mould Casting Co., Ltd.) is a Chinese industrial manufacturer specializing in glass molds for the container glass industry. Founded circa 1990 in Changshu, Jiangsu, the company operates a 40,000 square meter facility and self-positions as one of China's largest, highest-output, full-range, and best-quality modern enterprises in the glass mold sector. Its product range covers blow molds, press-blow molds, and narrow-neck press-blow molds, including forming, bottom, neck ring, mouth, and mouth ring molds, serving bottle, jar, and glassware manufacturers across beverage, pharmaceutical, cosmetic, and food applications.

The company's manufacturing is built on casting and precision machining: an automatic casting production line outputs up to 60 molds/hour in standard box sizes and is supported by three 500 kg iron melting furnaces, one 500 kg bronze furnace, and five heat treatment furnaces. Two laser welding machines enable spray welding without preheating, applied to neck rings and weld seams. Operations are organized under a 6S lean management model (SEIRI, SEITON, SEISO, SEIKETSU, SHITSUKE, SAFETY), introduced in 2021 alongside a 9-group QC competition system covering machining, assembly, welding, polishing, neck rings, lathe, milling, casting, and design. Quality inspection uses imported equipment (UK Penico series, Croatian HSTec water-soluble measuring machine, Japanese Mitutoyo precision calipers) under an ISO 9001 certified management system, with in-house design capability spanning bottle sampling, volume calculation, dimensional analysis, and 3D modeling.

Commercial activity is direct B2B: one-off sales of custom and catalog glass molds to container manufacturers, with revenue earned on a per-unit / per-order basis rather than recurring licensing. The company operates two sales channels — a domestic team (including dedicated internal trade for glassware / 器皿) and an international team (Sales Manager Max Jiang, Business Development Manager Leo Zhao, International Sales Assistant Lynn) — supported by WhatsApp and WeChat. The website and certain brand assets are credited to OMCO, a global glass mold producer, indicating a strategic or affiliated relationship that may serve as an international distribution lever. The company is privately held with no disclosed parent, investors, or funding events.
