Shoe Design: Process Analysis Of Shoemaking Process

First, Tailoring Technology



1, when receiving sample and sample shoes, prepare materials strictly according to the requirements of guests.



2, the dots, lines, and tooth defects on the pattern board should be painted on the materials painted, and the drawings should be consistent with the paper pattern.



3, when trimming, we should pay attention to the clipping curve cut smoothly, without gaps, and the lines should be cut off.



4. When painting materials, it is forbidden to use pen such as ball point pen or pen. It is not easy to erase the pen.



5, attention should be paid to typesetting accuracy, material saving and material direction, so as not to affect the effect after molding. Layout should first draw large panels, then draw small panels to save materials.



6, there are high frequency, electric embroidery parts, left and right directions should be cut more than 3-4 pieces. High frequency parts must be cut high foaming.



7. Cut it well. Material Science It should be done with rubber bands, put in plastic bags, the number of goods marked on plastic bags, customers, shoe last, size and so on, and then flow into the next process with sample and shoes.



8, do self inspection to ensure the quality of semi-finished products flowing into the next process.





Two, needle cart Technology



1, clean the machine and maintain the machine on time.



2. Understand the car before you sample it. List of goods Check whether the high frequency and electric embroidery match with the sample, understand the structure and vehicle method of the original shoes, and observe the cardboard. Problems should be found in advance, solved in time, and never allowed to be solved afterwards.



3, respond to punctuality, line, car cover point line does not exceed 0.8 - 1mm.



4, the edges should be strong, thin, and do not appear rough or loose.



5, needle distance 3 - 3.5 pin /cm, margin 1.2 - 1.5mm, row spacing 2-2.0mm.



6, the car's tongue and rear lining must follow the shape of the car. There is no deformation. The white lining should be covered with PE plastic protective film, and the line should be the same as the material.



7, the front of the weaving belt is used to roast the two ends of the torch to avoid tearing.



8, Bao Haimian, when the sponge should protrude the surrounding 5mm, do not pull too tight around the mouth, to be full and firm, smooth curve, if necessary, add foam and other materials, do not allow the sponge down.



9, the front port treasure stick to run 4mm from the side, just second lines of pressure side. This will not be easy. deformation After the phenomenon, the post Kong Bao is pasted at the 12mm from the foot of the gang.



10, the toe of the toe should be splicing. Sewing needle 3.5 - 4 pin /mm.



11, PU, the leather shoes should be rubbed and rubbed at the butt joint.



12. The distance between the sides and the feet is 2mm.



13, the appearance of empty belly should be rubbed firmly.



14, anti fur, PU Niu large area to add slice reinforcement, so as not to appear wrinkles.



15, encounter shelter, color difference, bad material, prohibit the use, unqualified high-frequency, embroidery and so on to stop production.



16, the good side of the car must be re examined, clean line, the same single, shoes to the management.



17, we should do well in the process of mutual inspection to ensure product quality.



Three. Molding process



1, when you receive samples of shoe upper and sole materials, you should arrange your homework in time.



2, net shoelaces should be worn to the right place: Men's shoes are worn to third, fourth holes, and children's shoes are worn to third holes.



3, we should match the number of shoe last and confirm the correct request before releasing the line.



4, the middle lining must be accurate, and there should be no misalignment.



5, the water and white latex should be brushed evenly, not too much water. The foot of the car must be at the edge of the net, not exceeding 2.5mm, and the same color line.



6, the shoe tongue and shoelace should be separated by cardboard, so as not to have shoelace marks on the tongue surface after molding.



7, before the clamp, press the shoe last adjusting machine to operate.



8, waist to tighten, hit the heel with high double.



9, before drawing the bottom line, first set the sole to see if it is covered with high frequency and embroidery. If you cover it, you should take measures immediately. When you draw the line, you must match the height with the double, and you can not appear the phenomenon of picture distortion. The shoe with a ribbon around it must be secured with the webbing.



10, brush the surface should not exceed the bottom line, brush evenly, no glue, many glue.



11, brush the bottom glue, do not spill glue, brush evenly, Huai long toe shoe rubber to brush the processing agent, the temperature should be adjusted well.



12, pay attention to the double bottom, do not skew, adjust the machine before pressing the bottom, grasp the time and pressure.



13, remove the last time to completely cool down before the last shoe, sample shoe last do not mix into production.



14. Shoes:



A, overflow glue;



B, shoe upper pollution;



C, thread edge;



D and degumming should be solved thoroughly.



E, the insole should be placed well, and the first piece of paper should be tightly pressed when the paper is stuffed.



F, wear shoelaces should pay attention to follow a direction can not reverse the phenomenon; G, finishing should be placed in plastic bags, one pair of flat, no heap pressure.
