Hongxin steel pill, trustworthy! Welcome to the Hongxin official website

In the foundry and casting industry, achieving flawless surface treatment is critical for product longevity and performance. However, many engineers and procurement managers face severe challenges during the shot blasting process. As the MALI — Pioneer of Intelligent Graded Abrasives, Wuhan Hongxin Lixin Metal Products Co., Ltd. provides advanced surface treatment solutions tailored specifically for casting cleaning. We help manufacturers transition from outdated, generic methods to intelligent grading, ensuring optimal abrasive selection for every unique application.

Core Pain Points in Foundry Surface Treatment

When dealing with complex castings, traditional abrasive blasting media often fall short. The industry currently struggles with three major operational issues that impact both quality and compliance:

1. Complex Internal Cavities: Removing molding sand and oxide scale from intricate internal cavities is exceptionally difficult. Aggressive traditional methods often damage the base material, leading to scrapped parts and significant financial losses.

2. Inconsistent Surface Roughness: Fluctuations in surface roughness severely affect downstream machining precision and coating adhesion. When roughness is not perfectly uniform, it leads to premature coating failures and costly rework.

3. High Dust Emissions: Stricter environmental regulations demand low dust and eco-friendly abrasive options to control sand removal dust emissions effectively. High dust levels not only violate environmental laws but also create hazardous working conditions.

Intelligent Grading: The Ultimate Surface Treatment Solution

To overcome these challenges, procurement teams must shift their mindset: purchase by roughness, not by chemical composition. Our intelligent grading system offers a custom graded abrasive solution with 4-level roughness grading (Rz 30-50/50-75/75-100/100-120μm). This precise abrasive mix ratio guarantees consistent results every single time.

By precisely controlling the particle size distribution, we eliminate oversized particles that cause deep, damaging pits, and undersized particles that fail to clean effectively. This tailored approach means you can specify your exact Rz target, and our team will formulate the perfect blend.

With 25 years of experience and participation in drafting 13 national and industry standards, we are the only abrasive company in anti-corrosion coating standards. Over the years, we have served nearly 4,000 manufacturing enterprises. By optimizing the cycle life and abrasive selection, our clients report that consumption reduced by 30% compared to traditional methods, with overall consumption as low as 0.42 kg/㎡.

Frequently Asked Questions

Q: What size steel shot should I use for Sa2.5 surface preparation?

A: For Sa2.5, S280-S330 shot is typical. However, the optimal size depends on your target roughness. MALI's intelligent grading system matches abrasive size to your exact Rz requirement.
