Roll Forming Machine

Roll forming machine was applied in large quantities Metal Roll forming is a continuous process.Roll forming is a continuous metal forming process that transforms sheet, strip or coiled metal into shapes with a consistent cross section. The stock is fed through successive pairs of rolls, which progressively shape the metal until the desired cross section is produced. Only progressive roll forming (bending) takes place; the metal thickness is not changed except for a slight thinning at the bend radii. the number of the roll former was different depending on the specification of the product. typical the number can be 8 to 30.the more the roll forming steps. the pressure divided into each one was small, duo to the efficien consideration, there is a balance point we should follow. that is way experience is important in roll forming machine products.

Roll forming is considered useful than the metal forming process, because fewer components needed to roll forming of waste materials have little patience closely rolled up to form a variety of materials. and lower production costs and they give more. Strength than the metal forming. The type of metal can be safe Where the winding up, giving users a variety of options in product design based on customer needs.

How to roll formed parts are manufactured to focus on the following industries - transportation, sporting goods store decor, mining, material handling industry, furniture, service industry, food industry, agriculture, construction, automotive and machine

Why Roll Forming

Roll forming is the process of saving and reproduce very closely agree with the length, width and detail section.

The following are the advantages of roll forming metal parts.
- Roll forming process allows operations such as punching, Bak, and access to the line. Wage labor and time for the two operations will be reduced or eliminated, reducing the cost of one

- Driving a Roll allows a high degree of flexibility. A single tool to roll the length of the almost the same cross-section of any multiple tools for different parts no longer needed.

Roll Forming Machine

- Roll forming can be controlled better than the competition dimension of other metal forming processes.

- Repeating a process that allows the assembly to occur more easily roll into the finished product and reduce the problems due to tolerance "standard" created.

- Roll forming is typically a high-speed process.

- Roll Forming customers with a surface finish better. This will roll forming a good choice for decorative parts, steel, stainless, or for parts to complete, such as anodizing or powder coating addition, surface or design that can be rolled into the surface during forming.

- Roll forming materials more efficiently than the other competition.

- Roll that can happen to develop some form of a wall than the competition process.

Roll Forming

The Process Roll Forming
Roll forming, sometimes spelled rollforming metal sheet metal forming process is a form of progress through a series of bending operations. The process is conducted in line roll forming sheet metal stock is fed through a series of roll stations. Each station has roller, roller means death, where both sides of the plate. Shape and size of the die roll may be unique to the station or like a death roll, many of which may be used in different positions. Wheels death may be the top and bottom sheet with sides, corners and other sheets are forced through the roller die stations, each coil is plastically deforms and bowed station roll each step in the completion of the bending of the plate. forms part of the requirements. Wheels are die lubricant to reduce friction between the die and sheet, which reduces engine wear. In addition, lubricants can allow a higher production rate, which depends on the thickness of roll stations, and the radius of each curve. Roll forming line also includes the performance of other fabricated metal plate before or after roll forming, such as punching or cutting.


The roll forming process can be used to form a sheet into a wide variety of cross-section profiles. An open profile is most common, but a closed tube-like shape can be created as well. Because the final form is achieved through a series of bends, the part does not require a uniform or symmetric cross-section along its length. Roll forming is used to create very long sheet metal parts with typical widths of 1-20 inches and thicknesses of 0.004-0.125 inches. However wider and thicker sheets can be formed, some up to 5 ft. wide and 0.25 inches thick. The roll forming process is capable of producing parts with tolerances as tight as ±0.005 inches. Typical roll formed parts include panels, tracks, shelving, etc. These parts are commonly used in industrial and commercial buildings for roofing, lighting, storage units, and HVAC applications.

Roll forming

Roll forming is a type of process which Metalworking operations continued to perform with bending This involves long piece of metal is moved through a series of stand-rolled coil sets, each roller of the increase in the total length of bend. Roll forming is continued until the cutting of metal that can be done. Roll forming process is very suitable for implementation of a long length and volume is required it is mainly used for many operations.

The use of roll forming stands, most of the array can be created across the metal piece. However, each of them must be set of tools that are designed specifically for the formings coil is designed generally with a flower like pattern that ends by setting the order of cross-section of metal, one for Each coil in the process of roll formed shapes formings roll created by the shape of the profile cross-section - series coil is charged very high though, and since this time, most types of technical models used for authentication. Correct coil design and reducing the stand and strain in the material roll forming process

Roll Forming

Current techniques used roll forming machine to create a cum-axis tracking profile or a new setting for all of the roll profile. Roll forming techniques are made in mills that are separated by the average middle of it and mount, webs, and the size of the ear is established with the help of control panel set to Roll medians formed as normal. configuration settings with a lot to win out over the system operating continuously. To cut out part of the length you want, medians are set for cutting the previous one died in the space to go through the mill rolls.

Cold-formed Sections

Sheet Metal เป็นวัสดุก่อสร้างที่กำลังได้รับความนิยมมากอยู่ในขณะนี้ กระบวนการหลักมี 2 ขั้นตอน

1) ขั้นตอนผลิตม้วนเหล็ก หรือ Steel Coil ขั้นตอนนี้สมัยก่อนเมืองไทยไม่มีเทคโนโลยีการผลิตในเรื่องนี้ ส่วนใหญ่นำม้วนเหล็กเข้ามาจากต่างประเทศ ประเทศหลักๆก็คงเป็นประเทศญี่ปุ่น แต่ปัจจุบันนี้มีทั้งนำเข้าและก็ผลิตในประเทศผสมกันไป...หน้ากว้างของม้วนเหล็กส่วนใหญ่จะใช้ 3 ฟุต (914 มิลลิเมตร) และ 4 ฟุต ความหนาที่ใช้บ่อยๆได้แก่ 0.4,0.5,0.6,0.8,1.00 มิลลิเมตร...ม้วนเหล็กดังกล่าวผ่านการเคลือบมาอย่างดีด้วยวัสดุเคลือบที่ป้องกันการเกิดสนิมบนเหล็กแกนในสุด(Base Metal) และถ้าต้องการสีตามที่สถาปนิกต้องการในเรื่องความสวยงามก็จะมีม้วนเหล็กชนิดเคลือบสีให้เลือก...แต่ราคาก็จะแพงขึ้น ถ้าต้องนำไปใช้ในพื้นที่(zone)ที่มีสภาพอากาศที่ทำให้เกิดการกัดกร่อนสูงก็จะมีม้วนเหล็กสเปกสูงให้เลือกขึ้นไปอีก คุณสมบัติหลักของเหล็กม้วนประเภทนี้สังเกตได้จากภายนอก จะดัดโค้งงอง่ายแต่จะเหนียวเพื่อให้ง่ายต่อการขึ้นรูปนั่นเอง...คุณสมบัติทางวิศกรรมก่อนนำไปใช้ต้องปรึกษาผู้ผลิตก่อน...เพื่อจะได้วัสดุที่เหมาะกับโครงการนั้นๆ สเปกจะได้ไม่สูงหรือต่ำเกินไป...คุ้มค่ากับค่าใช้จ่ายที่ต้องจ่ายไป

2) ขั้นตอนของการขึ้นรูป หรือ Forming (ในขั้นตอนนี้ผู้ใช้สามารถสอบถามสเปกม้วนเหล็กก่อนได้เพื่อให้แน่ใจก่อนตัดสินใจสั่งขึ้นรูป) ปัจจุบันในเมืองไทยจะเป็นบริษัทขึ้นรูปเสียเป็นส่วนใหญ่...โดยนำเหล็กม้วนเข้ามาเก็บไว้ในโรงงานของตน...มีทั้งบริษัทเล็กไปจนถึงบริษัทใหญ่ๆ

กระบวนการรีดขึ้นรูปมี 2 กระบวนการคือ

เครื่องรีดหลังคาเมทัลชีท

2.1) รีดเย็น (Cold Forming Steel Sheet) จะใช้รีดแผ่นหลังคา(Roofing),ผนัง(Wall & Clading),พื้น(Flooring) เครื่องรีดจะค่อยๆขึ้นรูปตามความยาวของม้วนเหล็กจนกระทั่งได้รูปลอนตามต้องการ สามารถรีดความยาวได้ตามต้องการ แต่จะถูกจำกัดความยาวด้วยข้อจำกัดของการขนส่งและวิธีการติดตั้งซึ่งทำให้รีดยาวมากไม่ได้...ต้องตัดแผ่นทำให้เกิดรอยต่อตามความยาวของแผ่น ซึ่งต้องออกแบบรอยต่อให้ดีเพื่อป้องกันการรั่วซึมของน้ำฝน

2.2) พับ (Press Braking) การขึ้นรูปโดยวิธีพับนี้ส่วนใหญ่ใช้กับบัวหรือคิ้ว (Flashing) เช่น ครอบสันหลังคา (Ridge Covering),ครอบหน้าจั่ว (Gable Flashing),บัวชายล่างของผนัง (End-wall Flashing)...ฯลฯ

Sheet Metal ยังมีเรื่องงานวิศวกรรมเข้ามาเกี่ยวข้องด้วย เช่นคุณสมบัติทางวิศวกรรมของหน้าตัด ซึ่งเป็นตัวกำหนดความแข็งแรงเพื่อนำไปคำนวณหาระยะห่างของแป หรือถ้าเป็นแผ่นพื้นก็สามารถคำนวณหาระยะห่างของคานได้...นอกจากนั้นก็ยังมีเรื่องของพื้นที่เกี่ยวข้องกับงานวิศวกรรมโดยตรงก็คือการนำไปใช้ในลักษณะของแบบหล่อคอนกรีต (Form-work) หรือใช้เป็นแผ่นพื้นเชิงประกอบรับแรงร่วมกับคอนกรีตที่เรียกว่า Composite Slab ในทางวิศกรรมต้องได้รับการออกแบบโดยวิศกรเพื่อความปลอดภัยขององค์อาคาร
