The Dilemma of Global Sheet Metal Factories: Why Deburring and Polishing Have Become Production "Stumbling Blocks"?

In the current era of fierce global manufacturing competition, sheet metal processing serves as a "cornerstone link" in core fields such as automotive, aerospace, electronic equipment, and medical devices. Its production efficiency and product quality directly determine an enterprise's global market competitiveness. However, a widespread yet insurmountable bottleneck is hindering the development of most foreign sheet metal factories — the inefficiency and instability in the metal deburring and polishing process.
Although core sheet metal processing links like cutting, bending, and welding have gradually achieved automation, industry research shows that more than 60% of sheet metal factories worldwide still rely on manual operations for deburring and polishing. This "semi-automated" situation not only reduces overall production capacity but also becomes a key factor eroding profits and causing missed orders. Through in-depth research on 100 sheet metal factories in Europe, America, Southeast Asia, the Middle East, and other regions, we have summarized three core pain points that plague these factories:

1. Manual Operation: Efficiency "Holds Back Progress" and Costs "Overwhelm"

Manual deburring and polishing are "routine operations" in many factories, but they hide unsolvable efficiency and cost problems. Workers need to repeatedly grind with tools such as files and sandpaper. For a standard 1.2m×2.4m stainless steel plate, it takes 15-20 minutes just for deburring; if a mirror polishing effect is required, the time is extended to 30-40 minutes.
Take a medium-sized sheet metal factory that processes 50 plates per day as an example. The deburring and polishing process alone requires 8-10 workers. Based on the average hourly wage of 25 in Europe and America, the monthly labor cost is as high as 35,000-40,000; even in Southeast Asia (with an hourly wage of 5), the monthly cost still reaches 8,000-10,000, which severely erodes profits in the long run.
More critically, there is instability in manual operations: differences in workers' technical skills and physical conditions lead to inconsistent deburring effects for products in the same batch, and it is difficult to unify the gloss and flatness of the polished surface. A German auto parts supplier once had a batch of sheet metal parts rejected by an automaker due to a 0.1mm precision error caused by manual polishing. This not only resulted in a direct loss of over $100,000 in orders but also damaged the long-term cooperative trust.

2. Traditional Equipment: Poor Adaptability and "Fast-Consuming" Consumables

Some factories that have attempted to upgrade their equipment have fallen into a new dilemma of "inapplicable traditional machines". Most traditional deburring machines are designed for a single material (e.g., only suitable for low-carbon steel) and cannot meet the "multi-material processing" needs of sheet metal factories. When processing metals of different hardness such as aluminum alloy, galvanized sheet, and titanium alloy, either the burrs are not completely removed, or the metal surface is scratched due to improper pressure control. Moreover, the grinding heads of traditional polishing machines are mostly disposable consumables, which need to be replaced after processing an average of 50 plates. The monthly cost of consumables exceeds $8,000, and the replacement process requires a 30-minute shutdown, further reducing efficiency.
The person in charge of a Southeast Asian sheet metal factory once said helplessly: "We bought 3 different traditional machines for stainless steel, aluminum alloy, and galvanized sheet respectively. They not only take up a lot of workshop space but also require special workers to operate each machine. The cost has not decreased, and the efficiency has become even worse."

3. Upgraded Global Quality Standards: Higher Order Thresholds

As the global manufacturing industry's requirements for "precision manufacturing" continue to increase, the surface precision standards for sheet metal products are also tightening. The EU CE certification requires the surface roughness of sheet metal parts to be ≤Ra0.8μm, and the US UL certification is even stricter, requiring it to be ≤Ra0.4μm. For sheet metal parts in the aerospace field, they even need to meet the extreme standard of "zero burrs + mirror polishing".
These standards are not "optional requirements" but "admission tickets" to enter the high-end market. Many sheet metal factories in Southeast Asia and South America have long been excluded from the supply chains of world-renowned enterprises such as Apple, Ford, and Airbus because they cannot meet European and American quality standards, and can only undertake low-end orders with meager profits.
It is the combination of these pain points that makes global sheet metal factories urgently need a deburring and polishing equipment that "can adapt to multiple materials, has high efficiency, low cost, and stable quality" — and this has laid the groundwork for the emergence of Dyyrent.
