JIAKE: Unleashing Efficiency with Advanced Expanded Metal Mesh Machines

Choosing the right machinery is the cornerstone of a profitable metal fabrication business. When it comes to expanded metal mesh, you need a machine that doesn’t just punch holes, but rather precisely slits and stretches steel plate into durable, high-yield mesh without producing any waste. JIAKE has established itself as a leader in this specialized sector, focusing on intelligent design and robust performance.

This article addresses the most frequent and critical questions potential investors and industry veterans have when considering a JIAKE Expanded Metal Mesh Machine.

1. What is an Expanded Metal Mesh Machine?

An Expanded Metal Mesh Making Machine is a specialized piece of equipment designed to manufacture mesh from solid metal sheets or coils. Unlike welding or weaving machines, this machine uses a unique process of simultaneous slitting and cold drawing (stretching).

Here’s how it works: high-precision blades punch a series of staggered, unattached cuts into a metal sheet. Immediately after the cut, the sheet is mechanically expanded or stretched. This action pulls the metal apart at the cuts, opening them into uniform, seamless openings (usually diamond or hexagonal shapes). The result is a single-piece, joint-free mesh that is significantly lighter than the original plate, yet incredibly strong and rigid.

The strength, lack of welds, and high material utilization make expanded mesh ideal for applications like industrial walkways, security barriers, filtration, and concrete reinforcement.

2. What Types are JIAKE Expanded Metal Mesh Machines?

JIAKE offers a range of models designed to handle different material thicknesses and mesh demands, categorized generally by their frame capacity and tonnage:

Light-Duty Series (6.3T, 16T, 25T): These smaller tonnage machines are optimized for thin materials (typically up to 0.2 mm to 1.2 mm thick), ideal for producing mesh for filters, small guards, and decorative ceilings. They prioritize speed and precise feeding.

Medium-Duty Series (35T, 40T, 63T): This is the most versatile range, handling materials up to 3.0 mm. These are the workhorses of the industry, capable of producing high-volume standard walkway mesh and robust fencing. They strike an excellent balance between speed, power, and cost-efficiency.

Heavy-Duty Series (100T, 160T, 260T): Designed for serious structural applications and large-scale infrastructure. These machines handle thick steel plates (up to 8.0 mm or more) to produce heavy-duty mesh used for mining support, heavy platforms, and bridge construction. These prioritize massive hydraulic or pneumatic force and structural rigidity.

High-Speed Series(GT10): This equipment can punch holes in sheets with a thickness of 0.1-1.0mm at a high speed, reaching 500 rpm.

3. What materials can an expanded metal mesh machine process?

Expanded mesh machines are designed to process various types of metal sheets because their core processes are punching and stretching, rather than welding or braiding wire.

The types of materials it can process depend primarily on the following factors: sheet thickness, hardness/strength, and ductility (whether the material can be effectively stretched without cracking).

Material type	Abbreviation	Common Applications	Key features
Low-carbon steel plate	Ordinary steel plate, black steel plate	Industrial walkways, building structures, safety fences, and machine guards.	Most commonly used and lowest cost. Good ductility, easy to punch and stretch.
galvanized steel sheet	Pre-galvanized sheet	Outdoor fences, ventilation openings, and areas requiring corrosion resistance.	The surface has a zinc coating, providing basic rust protection.
Stainless steel sheet	Stainless Steel (SS)	Filtration equipment, food processing, chemicals, medical equipment, and decoration.	It has extremely strong corrosion resistance, but its hardness is relatively high, requiring larger tonnage machines and wear-resistant molds.
Aluminum sheet/aluminum alloy	Aluminum	Ceilings, curtain walls, decorative panels, aerospace, lightweight structures.
copper coin	Copper	Decoration, electrical shielding, artwork.	It has good ductility and electrical conductivity. Care must be taken to maintain a smooth surface during processing.
Nickel plate	Nickel	Special filtration and battery components.	Extremely high corrosion resistance and high temperature resistance.

 

4. What is the maximum thickness and width of a steel plate that this machine can process?

Depending on the thickness of the sheet metal, we have designed various models of expanded mesh fence machines. When the sheet metal is thinner, you can choose a lightweight machine, which is lower in cost, smaller in size, and has lower transportation costs. When the sheet metal is thicker, you will need to purchase heavy-duty equipment. This allows you to select the appropriate equipment based on the sheet metal thickness. For the specific maximum steel plate thickness and width that can be processed, please refer to the expanded metal mesh machine equipment parameter table.

5. What is the maximum number of strokes per minute (SPM) for an expanded metal mesh machine?

The number of strokes per minute (SPM) for an expanded metal mesh machine depends on the model of the machine and the thickness of the sheet metal to be processed. Light-duty expanded metal mesh machines, used for thinner sheets, have a high punching speed, typically reaching 260-300 SPM; high-speed machines punch even faster, reaching 500 SPM; standard machines primarily process 0.2-3mm thick raw materials, achieving 75-110 SPM; heavy-duty machines process 0.5-8mm thick raw materials, achieving 32-60 SPM.

The thicker and harder the sheet metal, the greater the force required for punching and stretching. To protect the molds and equipment, it’s best to avoid reaching the maximum SPM value, preventing mold damage and extending the machine’s lifespan.

6. What are the minimum and maximum mesh sizes that an expanded metal mesh machine can produce?

Mesh size is typically measured in terms of short-way (SWD) and long-way (LWD) diamond shapes.

1. Minimum aperture size is primarily limited by sheet thickness and tool strength. Producing extremely small apertures requires very fine and sharp tool tips. This demands extremely high punching and drawing precision from the machine, along with long-life, highly wear-resistant carbide dies. Furthermore, the sheet thickness must be very thin (typically less than 1 mm).

2. Maximum Mesh Aperture: Maximum mesh aperture size is primarily limited by the machine’s stroke length and the feeding system’s capacity. Larger apertures require a longer feed distance per stroke, placing higher demands on the machine’s structural rigidity to ensure mesh uniformity during drawing.

7. What is the average lifespan of the die (cutting tool) for a steel mesh machine? Is the replacement cost high?

The lifespan of the die is affected by various factors, such as the hardness and thickness of the raw material, the mesh size (micro-mesh requires higher die precision, resulting in finer blades that are more prone to breakage or wear), the die material, the presence of a lubrication system to reduce wear, and the punching/shearing speed.

JIAKE expanded metal mesh machines use alloy die materials and have a lubrication system. Under normal operating conditions, the die lifespan is as follows:

High-speed/Light/Standard expanded metal mesh: Typically over 1.5 million to 3 million punches.

Heavy-duty expanded metal mesh: Die life is significantly shorter, possibly around 500,000 to 1 million punches.

Die replacement costs are generally high due to the high-precision machining and expensive raw materials involved. Die costs vary depending on the equipment model; please contact the JIAKE factory for specific details.

8. Is the JIAKE expanded metal mesh machine fully automatic? Is it equipped with a PLC control system?

Yes, the JIAKE expanded metal mesh machine is highly automated, requiring only one operator. JIAKE has developed a comprehensive expanded metal mesh production line, including an automatic uncoiler, leveler, flattener, slitting machine, shearing machine, and rewinder. It can automatically feed, punch, shear, flatten, and level, and perform slitting, cutting, and rewinding functions, saving labor costs.

Yes, the JIAKE expanded metal mesh machine is equipped with a PLC control system, synchronizing the movement of the punching cutters and the stepping of the stretching/feed system to ensure all processes work together seamlessly during high-speed operation.

The JIAKE expanded metal mesh machine is a highly automated production line driven by a PLC, which greatly improves efficiency and the consistency of mesh quality.

9. Can JIAKE expanded metal mesh machines change dies to produce different mesh shapes?

Yes, but you should consult the JIAKE factory for details.

The mesh shape depends entirely on the design of the cutting die. The cutting shape and the stepping/stretching mechanism together determine the final mesh shape.

For example, producing diamond mesh requires a standard V-shaped or straight-line cutter set; while producing special hexagonal mesh (or fish scale mesh) requires a more complex set of curved dies.

2. Common Replaceable Shapes

Diamond Mesh (Standard Diamond Mesh): This is the most common and standard shape.

Hexagonal Mesh: Typically used for decoration or special strength requirements.

Tortoise Shell/Flake Mesh: Primarily used for reinforcement or special applications in the petroleum, chemical, and construction industries.

10. What industries does expanded metal mesh primarily use in?

1. Construction and Structural Engineering: Expanded metal mesh is an essential material in the construction industry, mainly used for load-bearing, reinforcement, and partitioning.

Platforms, walkways, and stair treads: This is the most common application. Due to its excellent anti-slip properties (the mesh allows oil, water, snow, etc. to pass through), it is widely used in factories, oil platforms, ships, power facilities, and high-altitude maintenance platforms.

Concrete reinforcement: Especially heavy-duty expanded metal mesh can be used as a reinforcing rib for concrete or asphalt pavements, increasing the material’s tensile strength and crack resistance.

Walls and ceilings: As a base mesh (textured mesh) for plaster or stucco, it greatly enhances the adhesion of the plaster and prevents cracking.

Bridge construction: Used for pedestrian walkways or maintenance platforms on bridges, providing a safe and well-drained surface.

2. Safety and Protection: The high-strength structure of expanded metal mesh makes it an ideal protective material.

Security Fences: Used for partitioning and isolating high-security locations, factories, and warehouses; stronger and harder to cut than traditional welded wire mesh.

Machine Protective Covers: Used to cover mechanical equipment (such as rotating parts or high-temperature areas), providing physical protection without obstructing ventilation and visibility.

Window and Door Security Barriers: Used for window protection in banks, prisons, or high-risk buildings.

3. Industrial and Filtration: The continuous structure of expanded metal mesh makes it excellent for applications requiring stability and fluid control.

Filter Elements: Used as a support layer in air, liquid, or gas filtration systems, or directly as a coarse filter, its high porosity and robustness support finer filter materials.

Automotive Industry: Used as automotive grilles, exhaust system heat shields, or interior horn mesh covers.

Battery Electrodes: Used as conductive current collectors or electrode support mesh in batteries (especially certain types of fuel cells and accumulators).

4. Decoration and Aesthetics
Due to its unique three-dimensional appearance and light and shadow effects, expanded metal mesh is also used in architectural design.

Building Curtain Walls: Used as decorative panels on building facades, providing sun shading, ventilation, and a unique aesthetic effect.

Ceilings and Lighting: Used as suspended ceilings to conceal piping while maintaining ventilation and light penetration.

Display Shelving and Furniture: Used in commercial display cases, shelves, or modern furniture designs.

11. What is the warranty period for JIAKE expanded metal mesh machines?

Core Component Warranty: 12 months (one year). This is the industry standard warranty period, covering the main structure of the machine, mechanical transmission system, main motor, and hydraulic system (if it is a hydraulic press).

The warranty period is typically calculated from the date the machine arrives at the customer’s factory or is completed, commissioned, and accepted.

Electrical and Control System Warranty: 6 to 12 months. The warranty period for electrical components such as PLC controllers, sensors, and frequency converters may be slightly shorter than that for the main structure, as electrical components are relatively sensitive.

12. Does the JIAKE expanded metal mesh machine manufacturer provide overseas installation and operation training services?

Yes, as a professional Chinese expanded metal mesh machine manufacturer, JIAKE not only provides high-quality expanded metal mesh machine equipment but also comprehensive after-sales service.

After the equipment is transported to the customer’s factory, JIAKE dispatches a highly skilled technical team overseas to assist customers in installing, debugging, and quickly putting the equipment into production.

In addition, we provide free training services to ensure workshop personnel master operating skills, including routine maintenance, mold changing, lubrication, and feeding system adjustments.

Finally, the JIAKE technical team regularly visits customers overseas to maintain and repair equipment and resolve any issues.

13. What is the price of a JIAKE expanded metal mesh machine?

The initial purchase price of expanded metal mesh machines varies greatly, depending on the type of machine, tonnage, and level of automation you require.

1. The larger the tonnage, the higher the price. This is because a larger tonnage means the machine’s frame, transmission system, motor, etc., need to be made of heavier and more robust materials and have a more robust design to withstand the enormous impact forces. For example, a 100-ton machine will be much more expensive than a 30-ton machine.

2. Fully automatic machines with servo feeding are generally more expensive than semi-automatic or mechanical feeding machines.

3. High-speed models (such as 250-500 strokes per minute) are also more expensive due to the use of more precise parts and control systems.

4. The larger the maximum width or thickness of sheet metal the machine can process, the higher the machine’s cost.

5. Using well-known brand PLC control systems (such as Siemens, Mitsubishi), high-precision servo motors, and high-quality hydraulic or pneumatic components will all increase the cost.
