1. Industrial sewing box are made by a set of plastic parts (within a frame, a frame) and a set of iron - adapter (usually about a different).
2. The main points of our industrial framework two categories (plastic), 4 kinds of color.Different types and colors represent different brand.Barudan belongs to a category (plastic parts of the class there are a lot of screw holes), the rest of the brand belong to the same category (the three screw holes on both ends).In blue, the framework of Barudan Tajiam/Toyota box for the green, SWF framework for brown, Happy/ZSK Ricoma/Melco gray in color.
3. The brands, according to the scope of the embroidery machine arm width between different also.So every brand and points of different length.Because the plastic is a fixed length, so need to assemble different length of iron when it is assembled.
4. According to the size of the box, the framework of the same length, we divided into R9cm R12cm, R15cm, R18cm, R21cm, S24cm and S30cm. 12 cm, 15 cm and 30 cm is the best sell.
5. The meaning of the product code on the list.For example TA309, TA on behalf of the brand name, 3 represents the width of the Arm, 09 on behalf of the embroidery frame's size.But SWF need to pay attention to, because he has two dimensions between 400-500, so I use the distinction between A/B.
6. In these brands and their length is, the length of 360 mm is the most common.But when communicate with the customer, must ask they need length. 
7. Our framework (Tubular Frame) was mostly used to embroider the garment they machine.

Tajima ARM width is divided into 360 mm and 400 mm and 500 mm. Toyota main ARM width of 360 mm / 500 mm. The color for the green products, product serial number starting with TA.
(Tajima and Toyota use the same plastic and iron, so is the same product number).
