Qingdao Rinborn Machinery Co., Ltd

Company Overview

Who We Are

Qingdao Rinborn Machinery Co., Ltd, RMC, was founded in 1999 by our founding team based in Qingdao, Shangdong, China. With its foundry also in Shandong province, we have now grown to become one of the finest metal casting companies in the industry. With our fully organized facilities for casting and precisioin machining,  we utilize the new advanced technologies in all of our processes, which helps us produce complex, high precision, near-net metal parts from a range of ferrous and non-ferrous metals.

As a full-service investment casting company and with fully-equipped facilities, we have redundant manufacturing capabilities that enable us to produce top quality products for our customers in industry-leading turnaround times. We also offer outsourced casting capabilities, heat treatment and surface treatment in China to give our customers a lower-cost alternative with fast lead times.

Unlike a simple factory to produce parts, RMC, as a reliable strategic partner in the long run, is often fully engaged in its customer's cost reduction plans and casting supply chains.

RMC is a global-oriented manufacturer of high-precision, high-complexity and mission-critical casting and precision machined parts for diverse end-markets. We supply customized casting and machined products and provide surface treatment services to a well-diversified global customer base. Our global emerging position is underpinned by our integrated business model with comprehensive capabilities of offering one-stop solutions to our customers.

What We Do

RMC is an ISO 9001:2008 certified foundry and precision machining factory. As a professional provider, our capabilities mainly cover investment casting, sand casting, vacuum casting, forging and secondary process including machining, heat treatment, surface treatment, packing, logistics and comprehensive service in a wide variety of materials including gray iron, ductile iron, stainless steel, carbon steel, wear-resistant and heat-resistant steel, and various high alloy materials. Our dedicated quality control system ensures that our castings are produced to specification every time. We use the latest solidification modeling and software to predict and prevent problems before a single mold is poured. 

Our colleagues take it as a priority to understand the unique needs of our diverse customers from different industries so we can provide the suitable materials and castings to reach their requirements. RMC produces sand molds using the no-bake molding system, giving us great dimensional flexibility as well as the ability to pour castings up to several hundreds of kilograms. We can produce steel castings up to 0.5 tons and iron castings up to 1 tons. All melting is accomplished using a combination of channel induction furnaces and coreless induction furnaces. RMC stores customer patterns in a separate area away from the daily operation of the foundry. If necessary, we can produce patterns according to your drawings. 

No matter what you need single prototype parts or low or high-volume production runs, parts with a few grams or hundreds of kilograms, simple or complex designs—we are a Reliable Manufacturing Company that can do it all.
