Screen printing Industry is an important branch of the printing field, widely used in electronics, electrical appliances, advertising, clothing and other industries. With the rapid development of modern industry, automation equipment in the screen printing process is increasingly prominent role. The introduction and application of equipment such as tunnel Ovens, industrial Ovens and UV curing machines have greatly improved the efficiency, quality and stability of the screen printing process.

Screen Printing Process Introduction

1. The basic process of screen printing

Screen printing is a screen template through the ink transferred to the surface of the substrate printing method, the basic process includes plate making, printing, drying and curing steps. The process is widely used on substrates made of different materials, such as glass, metal, plastic and textiles, because of its wide adaptability and high printing accuracy.

2. Critical Steps in Screen Printing - Drying and Curing

In the screen printing process, ink drying and curing is a key step to ensure the quality and durability of the print. The efficiency and performance of the drying and curing equipment directly affects the quality of the print, production cycle and cost.

Application of Tunnel Oven Baking Equipment in Screen Printing Industry

• Principle of Tunnel Oven Baking Equipment

Tunnel oven is a continuous drying equipment, its principle of operation is through high-temperature airflow on the printed material is uniformly heated, so that the solvents in the ink volatilization and curing, to ensure that the adhesion and durability of the printed pattern. Tunnel ovens are usually equipped with a multi-stage temperature control system, which can adjust the temperature according to different materials and ink types to achieve the best drying effect.

• Technical Advantages of Tunnel Oven

1. Efficient production capacity

The tunnel oven adopts a continuous conveying method, which is able to quickly process large quantities of printed products and greatly improve the production efficiency. For products requiring continuous printing (e.g. electronic components, packaging materials, etc.), the tunnel oven is able to maintain a stable and efficient production to ensure the smoothness of the printing process.

2. Precise temperature control system

The tunnel oven is equipped with a multi-stage temperature control device, which can accurately control the temperature of different areas during the baking process, thus meeting the different drying requirements of screen printed products. This is especially important for printing products with multi-color and multi-layer patterns, as uneven temperature distribution may lead to ink distortion or pattern distortion.

3. Energy-saving and environmental protection design

Modern tunnel oven equipment usually employs energy-saving technologies that can reduce energy consumption and reduce pollutant emissions during the drying process through exhaust gas treatment systems. This environmentally friendly design is in line with the current trend of green manufacturing, and is particularly suitable for the screen printing industry, which requires high environmental protection.

• Tunnel furnace in the screen printing in specific applications

In the screen printing industry, tunnel ovens are usually used for drying the following types of products:

1. Glass Printing:Glass material usually requires high temperature resistant ink, tunnel oven can dry quickly at high temperature to ensure the adhesion of ink on the glass surface;

2. Textile printing:for T-shirt, fabric and other textile printing, the tunnel oven can prevent the printed materials from shrinking or deformation under high temperature by precise temperature control;

3. Electronic component printing:such as circuit boards and other precision electronic components, the tunnel oven can quickly curing conductive ink, to ensure that the conductive properties of the components and insulation.

Industrial oven in the screen printing industry applications

• The basic function of the industrial oven

Industrial oven as a screen printing process in another important piece of equipment, mainly used for printing after the drying, curing or heat treatment. Unlike tunnel ovens, industrial ovens are usually used for batch processing, suitable for those prints that are not suitable for continuous transportation. The oven is usually used inside the hot air circulation or infrared heating, can be uniformly heated on the printed materials.

• Technical advantages of industrial ovens

1. Adjustable temperature range

industrial ovens usually have a wide range of temperature adjustment function, according to the different needs of printing materials and ink types to adjust the temperature. Especially when dealing with thick or special materials, industrial ovens can provide more flexible heating options.

2. Uniform heating effect

The hot air circulation system inside the oven can ensure the temperature inside the oven is evenly distributed, avoiding the problem of localized overheating or uneven heating. For those products that need to be dried for a long time, industrial ovens can provide a stable drying environment.

3. Batch processing capacity

Although the industrial oven can not be as continuous as the tunnel oven to deal with printed products, but its advantage is that it can handle large quantities of products at the same time. The printed products can be put into the oven for drying at one time, and this batch processing method is suitable for the production of some small-lot, diversified products.

• The specific application of industrial ovens in screen printing

Industrial ovens in the screen printing industry applications mainly include:

1. metal material printing:such as stainless steel, aluminum alloy and other metal surfaces screen printing, industrial ovens can dry the ink at low temperatures to ensure that the metal surface is smooth and clear patterns;

2. thick material printing:such as wood, ceramics and other materials, its thickness is large, slow drying speed, industrial ovens can provide a long time uniform heating to ensure that the ink is completely cured.

UV curing machine in the screen printing industry applications

• Working principle of UV curing machine

UV curing machine is a UV light source through the UV ink for rapid curing equipment. UV ink is a kind of ultraviolet radiation will quickly cure into a film under the special ink, compared with the traditional heat-curing ink, UV curing faster, can be completed within a few seconds of the curing process.

• Technical advantages of UV curing machine

1. Ultra-fast curing speed

UV curing machine through high-intensity ultraviolet irradiation, can be completed within a few seconds of the ink curing process, greatly improving production efficiency, suitable for the need for efficient and rapid production of screen printing process.

2. Environmentally friendly and solvent-free

UV ink is environmentally friendly, does not contain volatile organic compounds (VOC), in the curing process does not produce harmful gases, the use of UV curing machine not only improves production efficiency, but also meets the requirements of modern environmental protection manufacturing.

3. Superior printing effect

Through UV curing, the ink can quickly form a hard film layer, which not only improves the abrasion resistance of the print, but also gives it a higher brightness and vividness. UV curing machines are widely used in industries that require high quality printing effects.

• UV curing machine in the specific application of screen printing

The main applications of UV curing machine in screen printing include:

1. Plastic printing:such as signs, packaging materials and other plastic products, UV curing machine can quickly curing ink, to prevent the printed materials in the process of handling scratches or pollution;

2. Advertising industry:advertising light boxes, signboards and other screen prints usually use UV ink, UV curing machine can provide high-quality printing results, to ensure that the prints are exposed to the outdoor environment for a long time without fading and wear.

Tunnel oven baking equipment, industrial ovens and UV curing machine is an indispensable key equipment in the screen printing industry. Through these devices, the efficiency and quality of the screen printing process has been greatly improved. The efficient production capacity of the tunnel furnace, industrial oven batch processing characteristics and UV curing machine rapid curing effect, so that the screen printing industry to meet the large-scale, diversified production needs.
