Shoemaking Process Management

First,

1, the daily raw and auxiliary materials entering and leaving the warehouse must do well the material account and stock account, and use the microcomputer to manage. 2, feed and deliver materials should be specially managed, so as not to make mistakes; 3, when feeding, there must be quality inspectors to check whether the quality is correct and whether the color is correct.

Two, cutting

1, the material should be assigned by the special person and assigned by the leader to the employees. 2. When the leather is cut, it can only be cut by single layer. The GSB-2C hydraulic swing arm type blanking machine or XCLP2-250 hydraulic plane cutting machine is better. 3, when cutting nylon cloth, special cloth, canvas and thinner PVC leather, because the material is soft and can be multi-layered at the same time, the XCLP2-250 hydraulic plane cutting machine or the XCLL2-250 hydraulic Longmen blanking machine is applied.

4, when cutting the middle floor, the material is hard, and it can also be multi-layered at one time. XCLP2-250 hydraulic plane blanking machine or XCLL2-250 hydraulic Longmen blanking machine is applied.

5, any cutting part, especially colored leather and cloth, should do quality inspection, color matching, double counting and quantity counting at the same time, so as not to repeat the work in the needle truck department. 6, the cutting supervisor should instruct the staff to do routine maintenance work for the machine and the knife mold. 7, the management personnel should always inspect the staff's use of chopping instructions according to the instruction number and instruct the staff how to self examine.

8, teaching staff to understand the material must be suitable for material application, and pay attention to chopping knife arrangement, reduce unnecessary waste of materials.

Three, allocate

1, the distribution center according to the order situation, will cut the good parts arranged neatly, waiting for processing; 2, the cutting parts need to print, peel, paste inside, hot stamping, etc., are responsible for the distribution center; 3, processed materials delivered to the silo spare parts group, from the warehouse material preparation team to the sewing machine workshop processing.

4, cutting parts such as the middle floor, insole and so on. If you don't need special sewing, you can deliver the semi-finished goods warehouse 5 to the distribution center after completing the necessary processing. After finishing all the components, you must properly organize the quality and statistics of all the parts of the vamp and prepare them for the sewing workshop.

Four. Management of needle truck workshop

1, the process and staffing configuration of the car help and help in the sewing machine workshop are changed according to the design of the shoe surface. Generally, a sewing machine assembly line can produce about 70-80 units every 8 hours, with about 10-15 hands for all kinds of sewing machines, and a total of 80-95 personnel. 2, when sewing, attention must be paid to the distance between the lines, whether the needle distance is well controlled, and whether it is consistent with the requirements; 3, when sewing, the correctness of the marking points on the shoe parts must be paid attention to, such as failing to follow the correct marks when sewing, and when the shoes are finished, it will not be correct, which will cause difficulties in the clipping and the quality of the finished shoes. The quality of the shoes will not be affected by the quality of the finished products. The results are as follows: (1500)

4, the sewing machine workshop must be equipped with small scissors and other tools. The shoe factory should purchase 5 of its own. The upper shoe must be inspected by the quality control department, and then the semi-finished product library will be sent according to the number of shoes required for each order, and the semi-finished product store will be sent to the molding workshop again.

6, instruct operators to maintain the machine regularly, so as to avoid the high failure rate of the machine and affect the quality and output.

Five. Shoe sole workshop management

In order to ensure the beauty of the finished products, the mould cost is high, the design shading should be in line with the popularity, so that the elimination time will be prolonged and the cost reduced. The injection materials (PVC, TPR, PU or EVA) should pay attention to their physical properties and ensure that the quality of the finished products is 2, and the rubber combination is made of the sole. The quality of the natural rubber should be paid attention to, and strive for stability. The ratio of various additives and chemical raw materials will affect the physical properties of the soles. The ratio and characteristics of the injection materials will change with the climate and processing time. They should be recorded as references at any time; the changes in the design of the sole must conform to the popular demand of the market; the rubber outsole should be stored in the dark place to avoid direct sunlight, and to avoid direct sunlight, and to pack them in black and white PVC bags, otherwise the aging products will affect the quality of the finished products. 1, molding bottom production: attention should be paid to precision.

In addition, the longer rubber outsole should be used first; the rubber outsole should be surface treated or rough before fitting, so as to facilitate adhesion.

Six. Semifinished product warehouse management

At the same time, the control of the material in the molding workshop is controlled. 3, before the side and sole are fed to the molding workshop, the semi finished warehouse managers must pay special attention to the quality control and quantity statistics work according to the process flow table. 4, each order must be made up of various materials such as the side, the middle, the bottom, the insole, the inner box, the outer box, the paper label, etc., and it can be sent to the molding shop 5. The daily production rotation number should be determined according to the number of the last set, the production workshop can receive 6 of the production schedule, and the schedule of the whole plant schedule 7. 1. Semi finished goods warehouse is the pfer station of the face and bottom process in the production of footwear. 2, semi finished goods warehouse management should be hurried to the sewing machine shop in time according to the scheduled time in the production schedule.

Seven. The management of clipping workshop.

1, the clipping process includes three parts: the front, the middle and the back. 2, the length and the length of the shoe bow should be in accordance with the standard. The color can be used to distinguish the length of the bow. 3, when the clips are used, the shoe upper part must be aligned with the shoe last.

4, when you are in the middle, you should pay attention to whether the two waist upper is really tight, and the tension should be moderate.

5, after the clip to help when we should pay attention to whether the heel height is in accordance with the standard, if each shoe heel height is in line with the last heel standard mark, then the finished shoes will not happen to the left and right foot shoes high inconsistency phenomenon.

After the help is finished, the middle nail should be taken off to remove the shoe last, so as to avoid injure the feet when wearing shoes.

6, the clipping process should set up a quality inspector to manually adjust and remedy the bad side of clips.

Eight. Rubbing and bottom molding.

1, pay attention to the accuracy of the marking board, so that the air pressure is about 0.

6MPa; 2. Rough grinding must remove the paint on the leather surface according to the radian after marking.

On the left and right sides, you must pay attention to the accuracy and uniformity of the glue and the bottom of the shoe. When the upper part is glued to the sole, the staff must pay attention to the bottom of the shoe. The shoes with the edges should be used as the bottom of the air bag or the three dimensional block press. When the bottom is pressed, the operator should pay attention to the correctness of the press. Meanwhile, pay attention to the control of press time (5-8S) and pressure (20-40KN) 8. When the bottom is finished, the sulfur shoes should be collected: the shoe should be collected in the sulfur tank for sulfur treatment; the cold sticky shoes must be put in the refrigerator and frozen. 3. The bonding surface of the big bottom must be treated with potable water 4 and the heating temperature should be 100 100.

9. After the bottom is pressed, the shoe is not completely cooled until it is finalized, so it is best not to remove the shoe last, so that the shoes will be deformed.

Nine, finishing and packaging
