Zhao Jicheng’s corresponding approach was implemented.
The dimensional error of the slitting material is required to be controlled within 0.1 mm, the dimension of the stripping is controlled within 10 mm, and the dimensions are inspected and recorded at any time.
When the sheet is broken, the blanking size of the reflective film required by the material notice is strictly 40mmX210mm. The error of manual cutting should be controlled within 1mm, and the error of machine breakage should be controlled within 5mm. In the process of breaking the same, it is also required to check at any time and finally record.
After the determined number and quality of the printed anti-reflective film are determined, the name of the blanking product is indicated by the coated paper strip, that is, the number, quantity, size and material batch number of the reflective crystal of a certain automobile or motorcycle, and attached The entire batch of material is positioned on top of the paper.
It is particularly important that the person in charge of the blanking process must carefully and responsibly fill in the batch number of the reflective film used on the production process sheet. The purpose is to avoid the inventory and the non-conforming materials in use, thus avoiding the greater Loss.
Third, the knife mold production is firstly designed by the design and development department according to the paper size of the reflective crystal sign 0300.5mm, the outer contour of the pattern is printed on the paper in the 6th imposition mode, and attached to the 5mm plastic plate to check the size of the circle. After confirming the correctness, hand it to the die-makers. After checking the correctness, use the sawing machine to cut the circle according to the die line, and the edge is required to be even and smooth.
After all the circular saws are used, the knife-forming machine of the 0.45X9.5 (mm) size made in Japan is embedded in the gap of the die line, and then the hand-cutting is carried out with self-adhesive backing paper or paper. Line, according to the paper size of the reflective crystal sign 300.5mm for measurement and inspection, requires no gaps at the interface, no misplacement, and need to be confirmed by the full-time inspection personnel, fill out the mold confirmation report.
After the die is finished, the foam is glued to the blade surface to protect the blade from being damaged by hard objects. Finally, the product name, date of manufacture, producer, knife template number, etc. are marked on the knife template, and the die cutting process is handed over.
According to the requirements of the production process sheet, the die-cutting personnel will receive the reflective film in the blanking process, check the quantity, and check whether the surface is scratched, etc., and fill in the picking list.
After the reflective film is received, the corresponding template is searched according to the knife template, and the quality of the die is checked. After the error, the pressure is adjusted according to the requirements of the product half-break, the spacing is from large to small, and the requirements of the paper are broken and the paper is continuously until.
During the die-cutting process, it should be strictly in accordance with the reflective crystal label inspection standard. The self-test ratio is 5%10%, and the qualified products and non-conforming products are separated. After the die-cutting is completed, the quantity is cleared, and each 100 sheets are separated by the bottom paper. , placed in the semi-finished area.
Fill in the production process sheet, and use the used die to return to the original place; if you find that there is a problem with the die, you need to fill in the repair order in time, and return the die cutter together with the knife template, and after each press cut, you must The date of the press cut, the quantity and the state of the die are indicated in the ledger.
5. Before the plastic injection, the finishing process to the die-cutting process requires the semi-finished products of the reflective film to be obtained according to the production process. It is necessary to clear the quantity and separate the qualified products from the non-conforming products.
It is required to check the quality of each circular label on each sheet, distinguish the qualified products and non-conforming products, and remove the non-conforming products to the waste paper, and fill the gaps in the qualified products. If you can repair it, fill in the repair order and return it to the relevant process.
Sixth, the plastic drop processbook1 plastic drop personnel receive the qualified semi-finished products after the waste, check the quantity, and check the quality.
Before the plastic injection operation, the workbench should be adjusted to the level, and the semi-finished products should be pasted on the glass plate. No defects such as bubbles and pastes should be present. The four corner finishing steps of the glass plate should be used to discharge the anti-cursor cards. The pads should be aligned with the four screw cap fulcrums, and the semi-finished glass plates should be pasted, preferably no more than 10 layers.
Imported crystal glue operation requirements as shown in Table 1 Table 1 Epoxy operation temperature A45±rcB28DC drip 33 soil rc crystal glue pretreatment vacuum tank feeding, vacuum filling nitrogen volume ratio volume drop plastic precautions mainly include: 1. Epoxy The interval should not exceed the alarm time. If the alarm time is reached, the plastic drop should be grasped; 2. The amount of glue should not be greatly fluctuated, and the thickness of the glue should be controlled at 2±0. 3. When the glue is finished after trimming, the surface of the print should not be scratched. Make it off the ink or appear patterns, bubbles; after the end of the glue, the top is covered with an empty glass plate, surrounded by silicone oil paper to prevent dust, impurities, etc.; on the silicone paper marked the name, date, Time, subpoena number, and fill in the product tracking form; after the work is finished, thoroughly clean the machine and mixer with methylene chloride. Wear a protective mask when cleaning. If there is solvent to the exposed parts of the body, rinse immediately with plenty of water.
Seventh, the final inspection stage finishing process according to the reflective crystal signage drawings and sample requirements one by one inspection, separate the qualified products, non-conforming products, and the full-time quality inspection personnel to sample the final product, fill in the finished product inspection report, production process records.
8. Packing and warehousing shall be packaged according to the packaging requirements put forward by the design and development department and the customer. After the packaging is completed, the certificate and signature shall be stamped, the date, name and quantity shall be marked and packed into the warehouse. The production technology department and the business department library management personnel handle the warehousing procedures, and the sum of the quantity of qualified products and non-conforming products is equal to the total quantity of the materials to be discharged. When the quantity does not match, the product identification and traceability procedures should be initiated until they match, and the relevant responsible person who caused the serious quantity non-conformity will be punished.
The finishing staff fills in the production process sheet and fills in the production process record and production report.
The above process of manufacturing the anti-cursor card of the automobile is written according to the requirements of the ISO9001 quality system for the work instructions, so it is also applicable to the standardization of the other types of screen printing products. The plastic products are colored and radiant. People, files, noble and other advantages are deeply loved by many consumers. As screen printing workers, they should actively improve the plastic drop process to win a larger market and benefits.
