Product Description
Company Profile of Hebei Tec-Sieve Wire Mesh Products Co., Ltd.
Hebei Tec-Sieve Wire Mesh Products Co., Ltd. ("Tec-Sieve" for short) is a comprehensive enterprise integrating production, R&D, sales and trade.
Tec-Sieve has the most advanced medium and heavy duty CNC punching machines in China, including high-speed gantry punches and supporting CNC shears and CNC bending machines.
In addition, we are also equipped with some high precision machines, including CNC turret punch presses.
Meanwhile, Tec-Sieve is equipped for many fabrication processess, including without limitation cutting to size, leveling, notching, bending, drilling, forming, welding, edging with matching strips and recoiling.
Our company specializes in the manufacture of punched plates, perforated plates and screen sieves.
At Tec-Sieve, we are equipped to punch a wide range of perforation patterns in a variety of materials including mild steel, galvanized steel, stainless steel, aluminum, aluminum-magnesium alloy, brass and plastic sheets, etc.
The perforation patterns we can do include without limitation round holes, square holes, round-end slotted holes, rectangular holes, triangular holes, hexagon holes, diamond holes and fish-scale holes.
For many years, perforated metal products our company has manufactured have been exported to developed countries and regions, including USA, South Korea and UAE. Our perforated metal products have gained recognition from overseas customers.
Round Hole Perforated Aluminum Flat Sheets
Materials:
Aluminum, and aluminum-maganesium alloy.
Hole patterns:
Description:
Tec-Sieve offers perforation of choice aluminum flat sheets. Perforated aluminum can provide a contrasting look with any non-perforated metal to create visual interest on any project. Architects can specify perforated aluminum to diffuse light, air or sound, or simply for architectural flair. Typical applications include equipment screens, partitions, sign panels, parking decks, guards, interior acoustical applications and enclosures of any kind.
Perforated aluminum is available in a nearly endless combination of hole sizes, spacing and open area percentages to complement virtually any architectural design or need. Perforation options will vary by panel profile and aluminum thickness; Please consult our factory for details.
Additionally, in terms of perforated aluminum flat sheets, our surface finishing processes include PVC powder coating, PVDF paint coating and anodizing, etc. in vertually any feasible RAL color to suit specific design and functional requirements. 
The most popular examples are shown below. 
Please consult our engineers for additional technical specifications not shown on the above chart.
Production Process of Round Holes Perforated Metal Mesh Plates
Step 1 Mold Design & Fabrication
The perforating process starts with the accuracy of mold design and fabrication. We have every confidence in the top quality mold that is principally responsible for top quality perforations.
Therefore in recent years, we have invested a lot of money in the mold design and fabrication, and now we have seen our significantly increased capacity to fabricate molds. Tec-Sieve has a large stock of molds, so ordinary holes patterns will not necessitate the remaking of new molds, and these molds are available directly from our storeroom of molds.
Step 2 Punching
We have the state-of-the-art CNC punching equipment, which are of 16MT, 25MT, 40MT and 80MT types. The daily output can reach up to 2000 square meters. Based upon different material types, the plate thickness usually ranges from 0.1mm to 10mm.
Step 3 Cutting
We have advanced CNC plate shearing machines, which can cut perforated sheets to any accurate sizes you desire.
Step 4 Edge Shearing
If in the production process the plate or sheet edge is out of your tolerance range, our skilled workers can help you remove the excessive edge upon your request.
Step 5 Levelling
We have 2.7 meters wide leveling machines, which enable perforated sheets to be as smooth as the original plates.
The perforated sheets with sheet thickness of 0.4mm to 5m can be levelled.
Step 6 Cleaning
The punching process necessitates the use of lubricants. However we also have an oil removal process, by which dirty marks on the surface can be removed. In this way perforated sheets will look very clean.
Step 7 Shaping and Deep Processing
We can also provide you with a series of subsequent processes, including levelling, cutting, labeling, packaging, deoiling, deburring, forming, annealing, painting, electroplating, welding, grinding, bending and coiling.
Step 8 Finishing
The processess such as punching, leveling and cutting can lead to imperfections on the surface of sheet metals, but these imperfections are acceptable in terms of general industrial products.
If you have special requirements, we will take additional measures to avoid such imperfections, and these measures include without limitation powder spraying or painting, electrogalvanizing, hot-dip galvanizing and anodizing.
Step 9 Packing
Many years of experience in the exportation of perforated metals has convinced Tec-Sieve that good quality products have to be companied by good quality packing, and in this way our clients can receive best quality products in the end!
