About Us

Dongguan Lean Industry Co., Ltd. (hereafter as "LeanIndustry") is a mould plant founded by Jack Hu, an experienced and passionate mechanical design engineer who has dedicated in mould industry for more than 20 years. 

LeanIndustry is registered in 2015 in Dongguan, a city in Guangdong province in China, to fulfill the growing needs from the domestic and oversea clients who pursue the best quality-price-ratio and innovation in the product design and manufacturing. 

LeanIndustry provides professional one-stop services according to clients requirements. We manufacture from provided drawings, and design new mould according to product sample or specification, with wide range of injection raw materials from common plastic, bakelite, to ceramics. We can also produce parts from client approved moulds, process finish treatment including: painting, silk screen printing, hot stamping, electroplating; and execute sub-assembly and packing for shipment if needed. 

We are proud of our nearly 100% customer satisfaction due to several distinguishing factors. On top of it, we are in a small but agile scale which can move quickly to solve problems and complete jobs while other larger companies get bogged down.

Plastic Injection Mould and Molding Parts

Mould Design | Injection

LeanIndustry has the capacity to run products in sizes up to 13” in a large array of materials. Among the thermoplastic materials utilized are standards such as ABS, PVC, Acrylic and Polycarbonate. Also used are specialized materials that can provide super high impact strength, withstand high or low temperature environments, or provide ESD protection. Many materials used are approved by various regulatory organizations such as FAA, FDA, NSF and UL.We also perform many post-processing operations including machining, assembly, and finishing. All operations are subject to rigid quality controls to ensure on time deliveries to clients. In addition, we maintain a network of stocking distributors, specialized fabricators, and precision machine shops that are constantly audited to maintain quality standards. This allows them to provide a full range of services to meet any plastic part requirements.

Precision CNC Machining Parts

Our CNC machining process uses 3- and 5-axis axis milling along with turning with live tooling to machine parts from more than 30 engineering-grade plastic and metal materials. The result is functional parts suitable for form and fit testing, jigs and fixtures, and end-use applications. Our automated CNC machining process can manufacture and ship up to 200 parts in as fast as one day.
