  1. Shot Peening: Enhancing Durability in Steel Parts

    Shot peening is a critical process in the manufacturing and maintenance of steel parts, particularly those subjected to cyclic tension and compression. Steel, while highly resistant to compression, is vulnerable to cyclic tension, which can lead to surface cracks and eventual breakage. Shot peening addresses this challenge by creating an artificial compressive stress on the surface of steel parts, thereby extending their lifetime and allowing for lighter parts with equivalent performance.

    Understanding Shot Peening

    Shot peening involves bombarding the surface of steel parts with small spherical shots, typically ranging from S110 to

  2. Effective Descaling Techniques for Coils and Plates

    Descaling in the metalworking industry, especially for coils and plates, is a vital process post-lamination. After being subjected to high temperatures during lamination, coils and plates often develop a layer of scale on their surface. This scale, if not removed, can hamper further processing and affect the quality of the final product. While acid bath treatments are commonly used, blasting is essential to maximize scale removal and prolong the life of these acid baths.

    The Challenge of Scale on Coils and Plates

    Scale formed during lamination is not just a surface blemish; it represents a significant barrier to quality and efficiency. The acid bath, while effective, can become less efficient over time due to scale buildup. Therefore, additional mechanical descaling methods are crucial.

  3. The Intricacies of Shot Blasting: Unveiling the Microscopic Details Through Slow-Motion Analysis

    A Slow-Motion Perspective

    The slow-motion video serves as an eye-opener, revealing how each high-speed shot impacts the sand-covered surface. The kinetic energy transforms into cleaning power upon impact, making it evident that achieving a clean surface is a result of millions of these tiny yet powerful interactions.

    Types of Shot for This Application

    When it comes to cleaning sand-covered surfaces, the type of shot used can make a significant difference. Here are some of the shots that are highly effective for such applications, and which you can find in our product range:

  4. Magnetic Cylinders in Shot Blasting: A Foundry-Specific Innovation

    How Magnetic Cylinders Preserve the Integrity of Shot Blasting in Foundries

    In foundry environments, shot blasting is a critical process for surface preparation and cleaning. However, the presence of foundry sand can pose a significant challenge, as it can contaminate the steel shot and compromise the effectiveness of the shot blasting process. This article delves into a specialized component of shot blasting machines designed to tackle this issue: magnetic cylinders.

    The Challenge: Foundry Sand

    Foundry sand is a necessary element in molding processes but becomes a contaminant during shot blasting. When mixed with steel

  7. TCO, Winoa's pillar of differentiation

    TCO, Winoa's pillar of differentiation  

     

    The TCO (Total Cost of Operation), or the "Total Cost of Operation" of sandblasting, is one of the pillars of Winoa's differentiation.

    Most companies think they can reduce the cost of blasting operations by buying cheaper abrasives. The problem is that, in reality, abrasives represent only 20% of the total cost of shot-blasting operations: therefore even a reduction in the purchase cost of the shot has little impact on the overall cost of the process.   Is there a more effective solution? Yes, considering all the elements involved: manpower, machines, maintenance, spare parts, wear, energy and waste, as well as the shot itself.

    ROUND STEEL SHOT

    Quenched and tempered, it is a spherical product of hypereutectoid steel (C ≥ 0,85%). Perfectly controlled heat treatments provide it with optimum resilience and resistance to fatigue. This type of shot is used in all applications where the desired effect is for mass and maximum bounce as well as for shot peening.

    ANGULAR STEEL GRIT

    A cast steel angular grit is produced by crushing specially heat treated oversize shot pellets. It is utilised for blast cleaning or surface preparation.

    GP STEEL GRIT

    Quenched and tempered, angular when new, this grit rapidly rounds off in use and is particularly suited to descaling applications.

  9. How to reduce your blasting costs

    How to reduce your blasting costs

     

    Every day, thousands of manufacturers around the world looking for new ways to reduce their production costs. Among the many dilemmas they face, there is one recurring question: "how to reduce the cost of my shot-blasting operations?"

     

    The problem is that, in reality, abrasives only represents 20% of the total cost of blasting operations. So even if you reduce the amount you spend by 10%, it will only ever translate as a 2% saving on the overall cost of the operation.

    Is there a better solution?

    Yes, by considering all the elements involved: manpower, machines, maintenance, spare parts, wear, energy and waste, as well as the shot itself. That's what we call the TCO approach : Total Cost of Operation.

  10. Ferrous and non-ferrous metals, How different?

    Ferrous metals

    Ferrous metals include mild steel, carbon steel, stainless steel, cast iron and wrought iron. These metals are primarily used for their tensile strength and durability, particularly mild steel which helps support the tallest skyscrapers and longest bridges in the world. You can also find iron and its alloys in house construction, industrial containers, large-scale piping, automobiles, railroad tracks, most of the tools and hardware you use around the house and the knives you cook with at home. 

    Due to the high amounts of carbon used during their creation, most ferrous metals and ferrous alloys are vulnerable to rust when exposed to the elements. While this is not true of wrought iron, which is so pure iron that it resists oxidation, or stainless steel,
