1. Distinguish the glued area
的 Distinguish the glued area of the product. This step is for us to distinguish the characteristics of each area of the product, to decide which parts of our products should be removed completely or not, and which parts should be removed half-off. The full-break area is usually removed, but there is also a support function for the convenience of the customer without removing the waste material. The half-break removes the waste material, and the release paper can protect the customer's product or Keep the product clean. If this is not the case, it is convenient to save labor in accordance with the manufacturing process, and it can be changed to completely off after communication with the customer.
2, the addition and position of the ear
Generally speaking, whether the ear is added or in which position is to be specified by the customer. If we want to add it ourselves, according to the principle of convenience, we say that the ear is added to the upper right area of the product. Small products can be added in the middle. In order to facilitate production, ears should be added at the highest point of the side line. If the line under the ear is straight, the direction should be straight and not inclined. The ears are gel-free, and small ears can affect the product.
3, size limit
Dimensional limit. The dimensional limit here is the size that we encounter when producing such a size that cannot be compensated by technology or has a great degree of difficulty that causes excessive productivity loss, such as: round holes below 1.5mm, frame distance within 1MM This type of die must have high accuracy before it can be completed. When small round holes are punched, it is easy to ** product waste and cause scrap.
小时 When the distance is very small, the foam of the pad cutter is easily crushed and becomes inelastic, which causes the product to deform, shift, or overflow, and easily fall off. At present, because the technology is not complete within 1mm of the circular hole die, the minimum distance between the inner and outer frames is required to be 0.8mm to produce the high and low blades.
But it can also guarantee the production. We can achieve a minimum distance of 0.4mm, and the tolerance is plus or minus 0.05 --- 0.1mm.
4, look at the front and back
The front and back sides here do not have to give the product a positive or negative side. What we want to distinguish here is which side is the first side when the customer uses the product? Our products are designed according to the design drawings provided by the customer The sequence of production is the first thing to understand.
Usually, the rubber surface that customers need to use first is lighter release paper, which is convenient for customers. When you have ears or positioning holes in double-sided adhesive products, the concept of "front and back" will be easily confused. Simply explain: the so-called front side is a complete finished product in front of you. When you see this side, you can clearly see that the side of the shape of the product is the so-called front side, and the other side that we can't see is called the reverse side or the rubber side.
The reverse side of a product with ears is the side that the customer wants to use first, and it is punched out with the front side facing up. For those with positioning holes, customers use the lighter release paper on the front side to stick the objects. At this time, the front side of our product is the rubber side, and some people call it the reverse side. In short, we need to determine which side the customer uses first based on the information passed on the customer's drawing. Subsequent design work can be carried out.
