Mark Material 


1、Introduction to Mark Material:

1. The purpose and significance of Mark Counting

Mark Counting is equivalent to the BOM bill of materials for some factories. It differs from the Bill of Materials in that the Bill of Materials is only the result, while Mark Counting also includes the process of calculation. It is based on The most economical and reasonable way to list the amount/cut of all materials required in the bag-making process and the location of the material on the bag.

Mark Material 



2. The role of mark metering:

A. Provide unit usage for calculating the material cost of the bag;

B. Provide a basis for purchasing materials;

C. Provide standard dosage for warehouse issue/production unit picking;

D. Provide cutting standards for material preparation personnel; E. Provide a reference for quality assurance departments and production units.

3. The basis of Mark's calculation:

A. Delivery orders: The delivery order includes the sample sheet/contact sheet/modification sheet of the business and some modification opinions of the guests;

B. Samples: samples include customer-generated samples/as-is/reserved samples, etc.;

C. Type version (and paper format);

D. In addition to the above three bases, in the absence of samples and paper sheets, sometimes estimates are based on drawings, so drawings sometimes become an important basis for calculating materials instead of samples and paper sheets.

4. The unit of mark material: The commonly used units of mark material are yards (Y) and inches ("), as well as CM/M/KG, etc.

5. The operation process of mark counting: bulk mark counting (single batch dosage/standard dosage) sample mark counting (unit dosage)

6. The composition of the marking material: the header and field header include: the finished product code/order number/product name/order quantity/SIZE/sample quantity/color number/production quantity, etc. Item number/name specification unit type version No. Specifications Horizontal * Straight Single Group Demand Single Bed Modality Horizontal * Straight Total Modality Denominator Numerator Remaining Material Ratio Standard Dosage

2、 Calculation of the main materials in the mark calculation:

Calculation of the main materials in the mark calculation: There are many methods for the calculation of the main materials in the handbag industry, such as the area method/typesetting method and the mark typesetting method, each of which has its advantages and disadvantages. The mark typesetting is divided into There are two cases, one is the regular piece layout, and the other is the irregular piece layout.

1. Regular cut piece layout: Regular cut piece layout, usually first measure the size of the original pattern or cut piece, and add 1/8" or 1/4" loss on this basis, depending on the specific situation (such as For materials with strong shrinkage, leave 1/4", otherwise leave 1/8"). This size is the specification in the Mark material (horizontal*straight). Then calculate the numerator/denominator according to the width of the material and the assumed length, and then calculate the Standard dosage or unit dosage, the calculation method is several pieces = width (length) of material/width (length) of cut piece (Note: rounded up as an integer) width of material (length) = width of a cut piece (length) * the number of pieces ( Note: The remainder needs to be added to an integer plus 1") The first formula is used to find out how many pieces can be arranged in the direction of knowing the width (length) of the material. The second formula is used to assume that X pieces of pieces are arranged Then find the width (length) of the material.

2. Calculation of irregular pieces: For irregular pieces, to achieve the most economical purpose, effective action is required - typesetting, also known as mark typesetting, that is, arranging the templates most economically according to certain rules. The maximum/minimum value is obtained by typesetting, which is the specification (horizontal*straight) in the material count, and then the numerator/denominator is calculated according to the material width and the assumed length combined with the following formula. Number of pieces=[width (length)-maximum]/ Minimum*2+2 Length(width)=(number of pieces-2)/2*minimum+maximum The first formula is used to find out how many pieces can be arranged in the direction of knowing the width (length) of the material. The second formula is used to find the width (length) of the material after assuming that the X pieces are arranged.


3、Measurement of auxiliary materials:

1. The auxiliary materials that need to be touched with a knife, such as an arc hook and loop fasteners, must pay attention to a certain direction and add 1/4" loss.

2. Materials such as webbing/hook and loop/elastic/PP rope/elastic rope that must be processed first and then sent to the production unit are usually measured and calculated according to the length of the actual material, especially the webbing used for reinforcement requires 100% Accurate (quantitative version)

3. Hemming tape (including webbing for hemming, the main material for hemming and cutting)/P-type pipe/elastic tape for hemming and other materials with a large loss of running 100 yards, should be measured on the template or sample during measurement After the actual length, add a 1~2" slack, depending on the specific situation.

4. The measurement of the 100-yard zipper is its actual length. If the zipper is longer, consider adding 1/8"~1/4" of width. The length of the strip zipper is the actual length between the two ends without leaving any width. Put. In the process of material counting, the zipper must be paid attention to that the zipper puller must be matched and must not be mixed.

5. When calculating the material of the fastener, attention should be paid to the material/specification.

6. Four snap-buttons/snap-buttons/eye buttons/strike nails/hollow nails/screws and nuts should be used together.

7. The measurement of special auxiliary materials, such as the elastic band of the side wall of the mobile phone bag will shrink after processing, so it needs to leave a 1/8~1/4" loss. In the process of wrapping the herringbone nylon belt, due to the large shrinkage Sometimes the loss will be as long as 5~8", etc., depending on the specific situation.


4、 Allowable loss rate:

1. When making bulk goods, there is a column of "allowable loss rate" in the Mark material. This allowable loss rate refers to a loss of external processing materials such as printing/embroidery/hot pressing/edge trimming. There is a specification for this loss The standard is to determine the percentage of loss based on the size of the order.

2. For materials such as snap buttons/snap-buttons/eye buttons/strike nails/hollow nails/screws/nuts, due to the large loss during the processing, it is also necessary to give the corresponding loss rate according to the order quantity.


5、 Issues to be paid attention to when typesetting and counting materials:

1. If the main and auxiliary materials are expressed in words during the material counting process, they must indicate their color/texture/specification, etc., and the full name should be used for the name, to distinguish similar materials and avoid confusion and mistakes.

2. Materials in special sections (such as oblique cutting/hedge trimming/glue/voltage, etc.) must be indicated during production, and those that should be lost must be lost.

3. Some special materials must be oriented in typesetting, such as velvet/mesh, etc., even if the material is not saved, they can only be typeset in one direction.

4. The width of the material (main material) cannot be used 100%, and a certain space needs to be reserved.

5. When counting materials for a bag, both main and auxiliary materials must be measured in a certain order, from front to back/top to bottom / from outside to inside / from left to right, so as not to miss or undercount. Counting materials, making the counting accuracy close to 100%.


6、 The rights, responsibilities, and obligations of the material planner:

1. The material counting personnel should complete their duties with due diligence, calculate the cost of the bag timely and accurately, and complete the quotation.

2. Have the responsibility to review the bag's beauty/function/sewing, etc., have the right to control the cost of the bag, have the right to object to the pattern maker's practice, and propose improvements to the lathe's sewing method.
