36氪 was informed that the casting grinding robot technology service provider “Quanyu Industry” recently completed a Pre-A round of financing of tens of millions of yuan. This round of financing is exclusively invested by Yunqi Capital, and the funds will be mainly used for product mass production, market expansion and other matters. Previously, it has completed tens of millions of angel round financing led by Northern Lights Venture Capital.
“Quanyu Industry” was established at the end of 2019. It is a high-tech company specializing in robotic grinding. The founding team has been focusing on the cleaning and grinding process of the foundry industry since 2012, and has been intensively cultivating robot technology in this field for more than 10 years, focusing on improving the grinding quality, solving the technical problems of casting deformation, mixed-line production and other industries.
The foundry industry is the mother base of industry, covering all industrial categories. As an important basic process in industrial production, casting has irreplaceable characteristics. According to the data provided by the China Foundry Association, in 2021, the global casting output will reach 109 million tons, of which China’s total casting output will reach 54.05 million tons, accounting for about 50% of the global casting output. According to the calculation of the grinding cost of 500 yuan/ton, the annual grinding cost of domestic foundry enterprises is at least 27 billion yuan with only manpower input, and the market certainty is huge .
Considering factors such as labor risks, labor costs, and the uncertainty of production organization, foundry manufacturers generally use labor outsourcing in the casting grinding process to solve production and management problems. Influence, exacerbated the contradiction between labor output and market demand.
Founder & CEO Wu Zhenyu said that after the production of castings, grinding is an essential process. However, due to its heavy working characteristics and harsh working environment, the high employment risk brought by pneumoconiosis leads to a huge shortage of personnel in this process and is extremely aging. Seriously, making automatic robot grinding a rigid demand in the foundry industry.
Due to the urgency of market demand, there are also automation companies trying to solve the problem of casting grinding through various means such as robot system integration or special machines. However, due to the high threshold for automation of the grinding process, there are many idle cases of grinding equipment in the market.
Wu Zhenyu told 36氪 that automatic robot grinding (casting) is definitely not only a simple robot + grinding wheel combination, but a systematic project. There are several major technical difficulties in casting grinding automation:
First, there are various types of castings, and each foundry enterprise has as few as dozens or as many as hundreds of products. It is necessary to provide flexibility to meet the precise grinding requirements of different types of castings. Second, the casting process leads to the deformation of casting blanks and the difference in grinding content. , as well as floating sand, sticky sand on the surface of the casting, iron pieces attached to the surface, iron cutting and other factors, which cause the grinding equipment to identify and accurately process the castings. Process and process and ensure that the equipment is capable of harsh working conditions.
Through more than 10 years of process precipitation and technology research and development, “Quanyu Industry” has developed standardized functional components such as grinding tool system, vision algorithm system, robot body, etc., and then realized the standardization of products.
From a process point of view, the company has developed a variety of rigid cutting and flexible grinding tool systems including casting casting riser cutting, venting and vent needle cutting, drape grinding, parting line grinding, deburring, etc. These tools can be freely Combination to meet all kinds of casting grinding needs.
From the software point of view, the company has developed software systems such as laser scanning grinding trajectory planning algorithm and grinding monitoring, and dynamically adjusts the robot trajectory according to the casting conditions to deal with the problems of casting deformation, efficient grinding and equipment safety.
Polishing robot products (from Quanyu Industry)
On the market side, the company has provided standardized grinding stations, line bodies and workshop-level equipment and services to a number of leading customers in various foundry fields such as Weichai, CRRC, ASIMCO International Foundry, and China Aerospace in the past two years.
Wu Zhenyu said that “Quanyu Industry”, with its technology and product advantages, will undertake a general contracting project of Weichai Power’s cleaning workshop automation with ABB and FANUC in 2021; At the same time, ASIMCO International Foundry has repurchased 7 phases of robot projects in a row to help complete the automation transformation of the entire grinding and cleaning workshop.
The company’s current profit model is equipment sales, and it is also implementing a piece-rate service model. According to the team’s research, it currently has more than 20,000 foundry companies and hundreds of foundry clusters. As well as the rapid occupation of market share through the technological transformation of old equipment.
