Ghana’s industrial heartbeat thrives on reliable energy. Yet grid instability remains a critical challenge, costing manufacturers productivity and revenue. When one of Accra’s leading metal fabrication plants faced escalating downtime, they turned to Besten. We didn’t just deliver a generator – we engineered resilience. This is how a ​500kW silent-type diesel generator​ with a robust ​Weichai engine​ became their operational lifeline, proving that intelligent power solutions can transform Africa’s industrial landscape.

 

The Reliability Equation: Beyond Basic Power

Traditional generators often fail Africa’s unique demands. Humidity corrodes components. Noise regulations restrict urban deployment. Intermittent operations strain engines. Our Ghana client needed more than kilowatts – they needed ​predictability.

 

Besten’s solution combined three key pillars:

1.Weichai Engine Durability: Tier 3-compliant technology optimized for high-ambient performance and 30% lower fuel consumption than older models.

2.Silent Operations: 75 dB(A) soundproofing allowed installation 100m from residential zones – impossible with standard generators.

3.Seamless Integration: Auto-transfer switches synchronized with existing systems, eliminating even 5-second interruptions during grid failure.

 

Why Silence Matters: Industry Meets Community

Africa’s industrial corridors often border communities. Noise pollution strains relationships and triggers shutdowns. Besten’s acoustic canopy technology ensured compliance with Ghana’s EPA standards while protecting social license to operate. The difference was tangible:

1.Plant workers could communicate without shouting

2.Nearby schools reported no disruptions

3.Vibration dampeners prevented structural resonance

This reinforced a vital truth: sustainable industry requires solutions respecting both production lines and neighborhoods. 

 

The Weichai Advantage in High-Stakes Scenarios

When the generator faced its ultimate test – an 11-hour grid failure during peak production – the Weichai engine delivered flawless performance. Engineered for continuous duty cycles, it maintained voltage stability within 0.5% variance under full 500kW load. Remote monitoring sensors gave engineers real-time diagnostics, preventing 3 potential issues before escalation. Post-event analysis showed zero derating despite 37°C heat – critical for African installations where temperature derating typically reduces usable capacity by 15-20%.

As Besten ships solutions from Nigeria to Mozambique, we’re standardizing features proven in Ghana: locally adaptable engineering, full-scope logistics, and partnerships with tier-one engine suppliers like Weichai. Because empowering Africa’s factories strengthens its economic sovereignty – one silent, reliable kilowatt at a time.

Since their invention in 1959, aluminum cans have revolutionized packaging with their strength, affordability, lightweight design, and aesthetic appeal. Today, they are ubiquitous across industries—from beverages to cosmetics. But what truly sets them apart is their extraordinary recyclability. Recycling aluminum cans isn’t just eco-friendly; it’s a powerhouse of efficiency. For example, recycling one ton of aluminum saves ​14,700 kg of CO₂ emissions​ and uses only ​4.86% of the energy​ required to produce new aluminum. Let’s break down how this process works and why it matters.

 

Step-by-Step Recycling Process

1.Crushing:
Used cans are first crushed to break down their original shape. This step prepares them for paint removal and increases surface area for efficient melting.

2.Paint Removal:

Crushed cans enter a de-painting kiln, where high temperatures (or chemical agents) strip away paint, glue, and coatings. This prevents toxic fumes during melting and ensures pure aluminum output.

3.Compacting:

Thin, crushed cans are compressed into dense bales. This reduces surface area, minimizing oxidation and metal loss during melting. A single bale can weigh over 500 kg.

4.Smelting:

Bales are melted in furnaces at ​700–750°C, transforming into molten aluminum. Impurities are skimmed off, and alloys (e.g., magnesium or copper) may be added to meet product specifications.

 

5 Key Uses for Recycled Aluminum Cans

1.Aluminum Ingots:

Smelted aluminum is cast into ingots, resembling "cooked aluminum." These serve as raw material for new cans or other products, reducing reliance on mined bauxite.

2.Alloy Production:

Recycled aluminum is blended into alloys like ​5052 (can lids)​​ or ​5182 (pull tabs)​. Its high magnesium content makes it ideal for strong, corrosion-resistant alloys.

3.Mixed Aluminum Ingots:

Lower-grade scrap aluminum is combined with recycled cans to produce hybrid ingots for non-critical components like automotive parts.

4.Steel Deoxidizers:

Aluminum powder from cans removes oxygen during steel production, improving metal purity and reducing defects in final products.

5.Low-Grade Aluminum Powder:

Decoated cans are processed into powder for fireworks, paints, or construction materials.

 

Conclusion: Small Can, Big Impact​

Aluminum cans are the superheroes of recycling—infinitely reusable without quality loss. By tossing cans into the recycling bin, we power a cycle where waste becomes resources, emissions plummet, and packaging stays sustainable.

1. Preparation and cleaning: A uniform and smooth surface is essential for the application of the anodized layer. You can achieve this through mechanical treatment and chemical cleaning. Mechanical surface treatment such as grinding and polishing that remove surface irregularities and defects. While alkaline or acid cleaning removes grease, oil, dirt and any other contaminants, followed by rinsing with deionized water to remove residual cleaning agents. Therefore, etching can be further cleaned to peel off the thin surface layer and create a uniform matte effect.

 

2. Electrochemical process: The part to be anodized next becomes the anode, and the other highly conductive metal becomes the cathode, and both are immersed in the electrolytic cell. When current flows through this electrolytic device, the anode oxidizes and loses electrons. During the electrolysis process, the metal surface is oxidized to form a dense oxide film. This oxide film is very hard and can protect the metal from further corrosion.

 

3. Coloring (optional): After the oxide film is formed, it can be dyed to give the metal surface a different color.

 

4. Sealing: The corrosion resistance and wear resistance of the oxide film can be further enhanced by sealing.

Engraving technology plays a significant role in modern personalised customisation and industrial manufacturing. Laser engraving and CNC stone engraving are two mainstream engraving methods, each with its unique advantages and application scenarios. We will delve into the core differences between these two technologies to help you make an informed choice based on your project requirements.

Core Technology Principles Comparison

Laser engraving technology utilises high-energy-density laser beams to induce physical or chemical changes on the material surface, achieving engraving effects through precise control of the laser path. This non-contact processing method is particularly suitable for intricate patterns and complex designs.

CNC stone carving employs three-axis or five-axis CNC machines equipped with specialised stone cutting tools or diamond needles. It removes material through physical cutting to achieve carving effects on stone surfaces.
Carving effects are achieved through milling and grinding.

Differences in Material Compatibility

Laser engraving compatible materials
Optimal materials: wood, acrylic, leather, glass, anodised aluminium, certain plastics.
Limited effectiveness on materials: transparent materials (requiring special treatment), certain reflective metals.
Not suitable for materials: chlorine-containing materials (e.g., PVC), certain materials that release toxic gases.

CNC stone carving specialises in
Natural stone: marble, granite, limestone, slate, sandstone, etc.
Engineered stone: quartz stone, engineered marble, concrete products.
Other hard materials: can also be used on hardwood, metal, etc., but the primary advantage lies in stone applications .

Processing Precision and Detail Reproduction

Laser engraving advantages:
Ultra-high precision: capable of 0.01mm-level detail.
Microscopic control: suitable for complex patterns and fine text (minimum font size of 0.5mm).
Non-contact processing: avoids errors caused by material displacement.
Production efficiency: quickly completes flat patterns without tool changes.
CNC engraving characteristics:
Typical precision: around 0.1mm, limited by tool size.
Three-dimensional representation: excels at 3D engraving with varying depths.
Large-scale works: more suitable for large-sized stone carving (e.g., tombstones, architectural decorations).
Production efficiency: suitable for large-scale stone processing, but tool changes take time.


Finished product effect and artistic expression

Laser engraving characteristics: Typically retains the original colour of the material, creating contrast through burning. Can achieve effects from shallow markings to deep engraving, but may be limited on stone. Can achieve gradient effects and grayscale image reproduction.

CNC engraving artistry: True 3D engraving, capable of expressing different depth levels with strong three-dimensionality. Can achieve various effects such as sandblasting and polishing through different tools. Suitable for large-scale artistic creations such as monuments and architectural reliefs.

Health, Safety, and Environmental Considerations

Laser engraving precautions: Requires a professional exhaust system to handle gases produced during engraving. Some materials may produce harmful substances during engraving, so laser safety equipment must be provided.

CNC stone engraving considerations: High noise levels require soundproofing measures. Stone dust is produced, so a dust collection system is needed. High-speed rotating tools require safety guards.


Laser engraving and CNC stone engraving each have their advantages. The choice depends on your specific materials, design requirements, and budget. Laser technology is evolving toward higher power levels, potentially expanding into more stone application areas. CNC engraving machines are developing toward multi-axis linkage and intelligent directions. The two may overlap and integrate in certain application scenarios.

Thin stone veneers are widely used in modern architecture and interior design, they are both aesthetically pleasing and practical, but they are prone to cracking during the cutting process.

Why do thin stone veneers tend to crack during cutting?

Thin stone veneers (usually 1-3cm thick) are prone to cracking during cutting due to their thinness. The main reasons for this are: the brittleness of the material itself, incorrect choice of cutting tool, incorrect cutting technique, lack of proper support, cutting too fast or under too much pressure.

The best choice of cutting tools for cutting thin stone veneer：
1. Wet cutter
Using diamond blades, the continuous water cooling reduces the particles and dust ejected during the cutting process and also leaves the finish very clean.

2. Angle grinder with diamond blades
Suitable for small jobs, must use wet cutting attachment and requires a steady hand.

3. Professional stone cutting saw
Thin veneer stone saw is a highly efficient machine designed for precision cutting of thin natural stone slabs for wall decoration, interior and exterior renovation projects. Its lightweight construction with a diamond blade makes it easy to cut thin stone veneer flats and corners , ensuring Its lightweight construction with a diamond blade makes it easy to cut thin stone veneer flats and corners , ensuring flat edges and reducing material waste. It offers high precision cutting of thin layers of cleaved surfaces or natural finished blocks of granite, marble, sandstone, limestone or brick. Easy to operate, safe and durable, mighty thin veneer saw is ideal for the stone processing and construction industries.

Cutting Tips and Precautions:

Ensure the stone is firmly supported: use rubber mats to reduce vibration .
Keep blades sharp: dull blades increase the risk of cracking and should be replaced if more pressure is needed to cut or if the kerf becomes rough.
Control depth of cut: Cut no more than 1/3 of the blade diameter at a time .
Temperature management: Avoid overheating and pause to allow the blade to cool if necessary .
Cutting for special shapes: For curved or complex shapes, consider waterjet cutting.

Precautions for different stones:
Granite: harder, requires professional grade blades.
Marble: softer but more fragile and requires special care.
Limestone: highly porous, cuts best when wet.

Cutting thin stone veneer requires the right tools, technique and patience. thin stone veneer saw is the most reliable option, reducing material waste and ensuring cutting accuracy. Thin stone veneer saws are the most reliable choice, reducing material waste and ensuring accurate cuts, but even with an angle grinder, good results can be achieved if the right steps are followed. The key to cutting thin stone veneer is slow and steady.

In the modern stone processing industry, stone polishing is a crucial process, which directly determines the gloss and beauty of the stone surface. There are two main polishing equipment on the market: manual polishing machine and automatic polishing machine. So, what exactly is the difference between these two types of equipment?

First, the work performance characteristics comparison
manual stone polishing machine:
manual polishing machine can be adapted to a variety of complex shapes and details processing, especially for deep holes, small grooves and other complex structures, manual operation is more flexible. However, the reliance on the operator’s experience and skills may lead to inconsistent polishing quality. Manual control of the polishing machine’s travelling path, pressure and speed is required. Usually hand-held or small bench-top machines, the polishing process is flexible but less efficient. Suitable for small batch, customised production. Relatively low cost.

Automatic Stone Polishing Machine:
Automatically operated by pre-set programmes or CNC system, it can accurately control the moving path, rotational speed and pressure of the polishing head. Mostly large-scale equipment, polishing process standardisation, high efficiency, reduce the cost of enterprise labour. Higher equipment costs and maintenance costs, suitable for standardised marble and granite plate batch processing of the production line.

Second, the choice of recommendations
Selected according to the output: daily output of less than 100 square metres can be considered manual, more than should choose automatic equipment

Consider the product type: regular flat stone is suitable for automatic polishing, shaped stone may need manual assistance.

Return on investment calculation: automatic equipment is expensive, but in the long run may be more cost-effective.

Evaluation of technical reserves: automatic equipment requires appropriate operation and maintenance personnel.

Future Development Considerations: If expansion is planned, automatic equipment is the more forward-looking option.

As technology advances, the two types of equipment are converging. Stone polishing machine is becoming more motorised and intelligent. Automatic equipment to add more flexible design, robot polishing system began to enter the market. Intelligent control systems can automatically recognise the type of stone and adjust parameters. Regardless of which equipment is chosen, keeping the equipment in good condition and using it correctly is the key to obtaining quality polishing results.

In the modern stone processing industry, the Bridge Saw has become an essential centrepiece of the granite and marble manufacturing process. This highly efficient and precise stone cutting machine has revolutionised the industry by revolutionising the way stone is traditionally processed. It is mainly embodied in the following aspects:
