Reflections on the training of shoemaking technology

I. Warehouse management of raw and auxiliary materials

1, daily raw and auxiliary materials in and out of the warehouse must do a good job of material accounting and inventory accounting, and microcomputer management; 2, feeding and distribution must be managed by special personnel to avoid mistakes; 3. When feeding, the quality inspector must be present to check whether the quality and color are correct.

Second, the cutting workshop management

1, picking goods must be handled by a special person and distributed to employees by the team leader; 2. When cutting leather, it is best to use GSB-2C hydraulic swing arm blanking machine or XCLP2-250 hydraulic plane blanking machine, because it can only cut a single layer; 3. When cutting nylon cloth, special Duo Long cloth, canvas and thin PVC leather, because the material is soft, multi-layer cutting can be carried out at the same time, so XCLP2-250 hydraulic plane blanking machine or XCLL2-250 hydraulic gantry blanking machine is used. 4. When cutting the bottom plate, because the material is hard, multiple layers can be cut at one time, and XCLP2-250 hydraulic plane blanking machine or XCLL2-250 hydraulic gantry blanking machine should be used. 5. Any cutting part, especially colored leather and cloth, should be checked, matched, matched and counted at the same time to avoid duplication of work when going to the sewing machine department; 6. The cutting supervisor should guide employees to do the daily maintenance of machines and molds; 7. Managers should check whether employees use seals at any time according to the knife number of the instruction sheet, and teach employees how to self-test. 8. The lecturer's understanding of the materials must be suitable for use, and pay attention to the arrangement of kopis to reduce unnecessary waste of materials.

Third, deployment center management.

1. According to the order, the deployment center arranges the cut parts neatly for processing; 2. If the cut parts need printing, peeling, lining and hot stamping, the deployment center shall be responsible for it; 3. The processed materials are sent to the Zhongcang Material Preparation Group, which sends the materials to the sewing machine workshop for processing. 4. If the cut parts, such as midsole and insole, do not need special sewing treatment, they can be sent to the semi-finished product warehouse after completing the necessary treatment. 5. In the deployment center, after all the parts are completed, the quality and statistical data of all the parts of the upper must be correctly sorted out and ready to be delivered to the sewing machine workshop.

Four, sewing machine workshop management

1. The technological process and staffing of sewing machine uppers and sewing machine uppers in sewing machine shops change according to the design of uppers. Generally speaking, if a sewing machine assembly line can produce 1500 double hours every 8 hours, there must be about 70-80 sewing machines and about 10- 15 manual workers. 2. When sewing, we must pay attention to whether the suture allowance and needle distance are well controlled and meet the required standards; 3. When sewing, we must pay attention to the correctness of each marking point on the upper part. If the correct mark is not pressed when sewing, the upper will be misaligned after finishing, which will make it difficult to clamp the upper and affect the quality of the finished shoes. 4. The sewing machine workshop must be equipped with tools such as small scissors, which are purchased by the shoe factory. 5. The finished vamps must be inspected by the quality control department, and then properly classified according to the shoe size required for each order, and then sent to the semi-finished product library, which will then send them to the sandwich molding workshop. 6. Instruct the operators to maintain the machine regularly, so as to avoid the high failure rate of the machine and affect the quality and output.

Five, sole workshop management

1, molding bottom production: attention should be paid to accuracy to ensure the beauty of the finished product; The cost of mould is high, and the shading design should conform to the fashion, so as to prolong its elimination time and reduce the cost; Injection molding materials (PVC, TPR, PU or EVA) should pay attention to their physical properties and do more tests to ensure the quality of finished products. 2. Rubber combination outsole production: pay attention to the quality of natural rubber and strive for stability; The mixing ratio of various additives and chemical raw materials will affect the physical properties of the sole, and its ratio and characteristics will change with the climate and processing time, so it should be recorded at any time for reference. The change of sole pattern design must meet the needs of market popularity; Rubber outsole should be stored in a dark place to avoid direct sunlight, and packed in black and white PVC bags, otherwise it will age and affect the quality of finished products. In addition, the rubber outsole with long storage time should be used first; Rubber outsole should be treated with surface treatment or rough treatment before bonding to promote bonding;

Six, semi-finished products warehouse management

1. Semi-finished products warehouse is a transfer station for the surface and bottom processes in the footwear production process. 2. The management of semi-finished products warehouse should promptly urge the sewing machine workshop to produce according to the time arranged in the production sequence table, and at the same time control the delivery of materials in the quilting workshop; 3. Before the uppers and soles are sent to the molding workshop, the semi-finished warehouse manager must pay special attention to quality management and quantity statistics according to the process flow chart. 4. Each order must be prepared with various materials such as vamp, midsole, outsole, insole, inner box, outer box and paper label before it can be sent to the molding workshop. 5. The daily production turnover should be determined according to the number of trees finally ordered, and the molding workshop will receive production according to the form.

Seven. Workshop management of side clamp forming

1. The upper clamping process includes three parts: front upper, middle upper and rear upper. 2. The wearing mode and length of the arch should meet the standards and be used in sections (the length can be distinguished by color). 3. When clamping the front upper, special attention must be paid to the alignment of the upper and the last, and it is not allowed to be skewed. At the same time, pay attention to the standard height after fixation.
