How To Reduce The Process Loss Of Cutting Leather

The production of high quality shoe factories requires very high quality of products, especially cutting operations, which cause high loss of leather. Therefore, how to reduce wastage must start with cutting.

Almost every management class wants to reduce costs, but the shoe making procedure is so complicated, and the quality requirements of traders often make managers and operators at a loss. When the traders are strict with the inspectors, the on-site defective rate will be improved. Although the products produced are able to meet the requirements of customers, they also pay a heavy price, such as the downtime of the production line and the inability to confirm the quality standards. Therefore, in order to effectively reduce the leather loss of the process, it is necessary to establish the basic quality improvement measures.

Shoemaking is a labor-intensive and relatively low technology industry. However, due to the training of personnel, the improvement of manufacturing process is not complete, resulting in high attrition rate.

Therefore, the steps to reduce the loss of leather manufacturing process are as follows:

Education and training are the most important conditions, especially the basic education.

In the United States, the process cutting hands are regarded as senior engineers, because this job must have professional knowledge, judgement, agility and digital concepts, and it is also the source of deciding whether a pair of shoes is good or bad. But the domestic cutting hands can not be rooted in the basic cutting technology due to the influence of the production environment, such as rush production, record keeping and requirements for traders, which is the shoe factory must improve.

Education and training must be divided into two principles, namely, the instructors must teach leather material selection and typesetting technology. Management must teach cost control and management methods. A good cut must be technology and management at the same time upgrading, so that quality and efficiency will be improved.

Guidance is to establish standardized operation, and all processes are consistent.

The most important thing in managing shoemaking factories is to manage standardization and standardization. However, due to the operator's proficiency and knowledge of leather, the standardization of movement is more accurate. The standardization of cutting actions is carried out at the angle of management. The standardization procedures are as follows:

1. Each operator has the same opinion on the selection of leather materials.

Two. Every operator knows the shape of the cutters very well.

Three. Every operator knows very well about typesetting technology.

Four. Every operator knows very well about the first knife.

Five. Every operator knows very well about double matching and flow marking.

Six. Every operator is consistent with provincial practice.

Seven. Every operator knows very well about the requirements of traders.

Eight. Every operator knows the quality standard very well.

Nine. Every operator knows very well the requirements of the manager.

Ten. Every operator can implement the quality, efficiency and work standardization step by step according to the requirements.

If the operator's cutting technology is right, it can save about 5% to 7%, which is very helpful for leather materials.

The specific practice of typesetting is to continuously demand that effective control of the cost of cutting must be continuously demanded and checked continuously. It must be divided into three stages. First, the establishment of standardized technology, followed by checking the application of each operator, and finally, checking the differences between them and reviewing the improvement measures.

Project content

According to the experience of counselling, we should first establish the right leather material selection technology in the leather material saving, and then train to become a superb typesetting expert.

First, leather material selection according to the actual leather (semi leather) to explain the quality level, the choice of blemishes, the choice of different materials, each operator must be very aware of the characteristics of leather.

Two, typesetting technology must understand the typesetting skills, such as straight alignment, radian to radian, first blade location, convex concave concave, concave convex, no corner cutting, square cutting and three knife method.

Three, for on-site improvement, the concept of operator must be implemented to the technical level, and the consumption of leather materials should be reduced continuously on the basis of inspection.

The technology of cutting management and the key points for attention

For managerial cadres, cutting must pay attention to technology, management of needle cars should be paid attention to and management of cadres should be paid attention to, while forming cadres should take account of the two aspects. Therefore, the management cadres in shoe factories must understand the needs of management. In addition to correctly dispatching workers every morning, inspecting the scene must be a key management position. The most important thing is to inspect the operators' leather material selection technology and the technology of cutting row in the morning, but not to see whether the products meet the quality requirements. Therefore, the principle of improving the site must pay attention to finding a reasonable standard production capacity for each operator, setting standard cutting time for each reasonable production capacity, and checking whether there is material waste and waste of typesetting technology according to the standard operation time.

Education and training curriculum capacity

Education and training project education training content education training

Implementation time

The selection of leather material is the most important part of the education and training for operators.

Description of leather quality and defects and 36 hours' understanding.

Dermis grade

Typesetting technology is the most important training for operators.

The content is a practical drill for arranging knives, saving material and correct for 72 hours.

Teaching principles

Material calculation is the most important method for the management and training of management cadres.

The utilization rate and wastage of all kinds of cutters are 36 hours.

train

Cost control is mainly for 36 hours after training for management cadres.

The contents should be the control of the cutting collar material and the revision of the printing plate.

Cutting management for management cadres before and after the education and training, 72 hours.

The main contents are field management and control process training.
