In the dental implant industry, SLA (Large-grit Sandblasted, Acid-etched) surface treatment has become the "gold standard" process determining implant quality, osseointegration speed, and long-term stability. As the core carrier of this process, acid etching and cleaning equipment directly dictates whether implants meet medical-grade mass production standards in terms of precision, cleanliness, stability, and automation.

Across the domestic market, Hualing Kena (CSE) stands out as a preferred brand in SLA dental implant surface treatment equipment, backed by profound semiconductor wet processing expertise, medical-grade customization capabilities, and exceptional cost-effectiveness. It provides domestic high-end implant manufacturing with localized solutions matching international benchmarks.

I. Technical Foundation

• Ultraclean Control: Adopting semiconductor wafer cleaning standards, it uses multi-stage DI ultrapure water rinsing, ultrasonic cavitation cleaning, and vacuum-assisted cleaning to completely remove residual alumina from sandblasting, acid residues, and microparticulate impurities. This meets the zero-contamination and high-biocompatibility requirements of medical implants.

• Precise Parameter Control: A fully programmable PLC control system enables digital closed-loop control of acid etching temperature (±0.5℃), time, concentration, stirring rate, and spray pressure. This ensures uniform secondary micro-pits of 0.25–0.5μm on each implant surface, increasing the osseointegration area by over 60%.

• Highly Corrosion-Resistant Materials: Tanks, pipelines, and valves are all made of high-purity PFA, PVDF, quartz, and other HF/mixed acid-resistant special materials, eliminating metal ion precipitation. It adapts to the dedicated hydrochloric acid + sulfuric acid + hydrofluoric acid mixed etching system for dental implants, with a service life far exceeding ordinary industrial-grade equipment.

II. Product Advantages

• Customized Process Adaptation: Tailors complete equipment treatment flows to actual production processes of implants of different materials and specifications, adapting to diverse production scenarios and flexibly meeting mass production and customized manufacturing needs.

• Flexible Multi-Type Fixtures: Supports free switching between circular and square fixtures, with stable clamping and easy access. It adapts to batch continuous processing and effectively improves production efficiency.

• Intelligent and Accurate Fluid Preparation & Replenishment: Equipped with an automated fluid control system, it enables automatic liquid transfer from stock barrels to weighing barrels. Dual precision control via metering pumps and flowmeters fully automates fluid preparation and replenishment, stabilizing the chemical ratio accuracy at 1–3% to ensure consistent treatment effects for each batch.

• High-Corrosion-Resistant High-Purity Tank: Constructed from high-purity corrosion-resistant special materials, the tank delivers excellent resistance to strong acid corrosion, stably adapting to harsh chemical environments including hydrochloric acid, sulfuric acid, nitric acid, and hydrofluoric acid. It is corrosion-resistant, easy to clean, long-lasting, and greatly reduces equipment operation and maintenance costs.
