Forward supply, forward service
Our raw materials are selected from the best materials in the market, and our suppliers are all well-known enterprises in the industry.There are two kinds of materials for the bottom cover, tinplate and black plate, both of which are from Baosteel and SHOUGANG GROUP, which are the largest and most modern steel joint enterprises in China, providing us with high quality and guaranteed iron materials.
Cold rolling and hot rolling substrates followed by acid pickling, oil removal and a series of processes, to obtain suitable coating clean surface, get high quality substrates and tin materials, but also for subsequent processing coating provides a high quality foundation.
As a result of environmental protection to promote water-based paint, now the use of double-coated substrate manufacturers more, but tinplate compared to the substrate, has a stronger corrosion resistance, light permeability, made of the bottom cover can better extend the service life of the coating. BOPET film with surface adhesion is purchased from Sanfangxiang group. Compared with other films, BOPET film has better barrier, heat resistance, high strength, good rigidity, transparency, high gloss, colorless, non-toxic and other characteristics.
The equipment for lid making is blanking punch, molding punch, rubber strip machine, cover injection machine.
And for bottom making is blanking punch, molding punch, round edge injection machine.
The all-in-one rubber strip/glue injection machine independently developed by our company can be used in the same machine as the automatic rubber strip loading and glue injection, which greatly saves time cost , resource cost and higher efficiency.
With glue injection on the cover, an additional set of glue drying room is needed, which can quickly dry the glue and shorten the production cycle.The glue drying equipment of the cover is generally called gas chamber. The glue is dried and foamed in it, and the temperature is maintained at 200-220 degrees Celsius to make the glue foamed successfully.
The drying room has the characteristics of stable temperature, and the foamed glue injection strip also has better elasticity.
The bottom can be dried by equipment or left to air dry. The glue drying equipment at the bottom adopts electric heating and drying room, the temperature is kept between 60 and 80 degrees Celsius, the use of drying room, can make the glue drying quickly, good stability,and no bubbles.
Professional procurement personnel: procurement personnel have sensitive market judgment, can timely understand the commodity information, give detailed sales data analysis, to provide the company with good quality, low price products, so as to create high profits. At the same time, they also understand the knowledge related to logistics, and can actively communicate with logistics about the arrival time of materials and cooperate with production.If there is a shortage of raw materials or parts, they can timely report and deal with the problem, so as to avoid the same problem next time. Emphasize the quality and outer packing with the supplier before purchase to avoid unqualified goods.
Become a VIP customer of many suppliers, establish strategic cooperative partnership with many suppliers and trust each other. So won't appear the shortage of raw materials, can guarantee the delivery date. If you have urgent orders, we can immediately place an order with the supplier, and ask the local supplier to give us priority to arrange raw materials or accessories, without delaying production.
Benign payment method: as we are a VIP customer of many suppliers, both sides have reached a consensus on the payment method. Therefore, there will be no trouble in production and supply due to the payment problem.
Drawing of standard workmanship,mold of precision；measuring with caliper or depth gauge in strict accordance with customer's requirements.
Manual inspection is conducted in all links；inspection of semi-finished products and finished products. For lid height, outer diameter, inner diameter, counter deepth and other dimensions, are strictly controlled within the range of customer requirements.
The finished product is tested by naked eye observation method, which is 0.5m away from the product under the fluorescent lamp.
The inside and outside surface is clean, flat, without color difference or edge curling.
Control in the production process ---1) ensure the lubrication of the mold is in place, 2) check whether there is a gap between the mold and the raw material ,too big or too small, 3) during the conveying process, check the parts regularly which have direct contact with the iron surface in the production process, such as punch press, punch, conveyor belt, upper and lower die core, blank holder ring, forming outer frame, and so on, to keep the iron surface highly smooth and free of foreign matter.
First of all, grasp the control of raw materials. Qualification inspection of raw material in storage after entering the factory. The biscuit of each roll of materials are inspected, to ensure the quality of raw materials coating qualified. Strictly control the production process, check the machine regularly, do not touch the product arbitrarily.
Mainly lies in the raw material laminating qualified, followed by the random inspection of semi-finished products in each production process.
For this purpose, we usually take the following sampling tests:
1) Sampling inspection of raw materials arrival, take the destroy cup crown test, observe whether the film is broken or separated from the plate.
2) After molding, take the secondary destroy cup crown test,to observe whether the film is broken or separated from the steel.
3) Acid and alkali brine test (sodium hydroxide + industrial salt) of finished product, immerse it for 7 days, and observe whether there is rust, blistering or black spot.
Take the acid and alkali brine test (sodium hydroxide + industrial salt) on raw materials and finished products, immerse them in acid and alkali test water for 7 days to observe whether there is corrosion on product surface.
Other defects, such as color difference, oil spots on iron surface, white spots on transparent film and so on, shall be controlled through the factory inspection of raw materials, manual feedback in the production process, and regular random inspection.
Sealability of EVA sealing ring: solvent resistance of EVA sealing ring test (butanone & toluene) Sampling inspection of EVA sealing rings arrival, it is firstly confirmed by the naked eye whether there are obvious quality problems, and then it is soaked in butanone toluene solvent, and the cycle is 7 days to test the tightness and elasticity as well as whether it is corroded.
EVA sealing ring joint: Automatic gluing machine is adopted in the production process to avoid the uncertainty of manual gluing. After the strip with naked eye observation method, confirm that the joint is firm, no cracking phenomenon.
Sealability of glue injection: The lid is dried by gas drying room, and the bottom is dried by electric heating drying room, which can have better stability. In terms of the stretch length of glue injection, attention should be paid to the quality of glue raw materials, glue ratio, control the width of glue spraying (amount of glue injection), and finally ensure the sealing of glue injection.
The warehouse is mainly divided into: raw material warehouse, accessories warehouse, equipment hardware warehouse, semi-finished products warehouse, finished products warehouse, defective goods warehouse, and sample warehouse.
Requirements for raw material warehouse:
Keep clean and dry, pay attention to damp proof, Ventilation cooling and damp reduction, set up separately.

Classified according to type and color, clearly marked, convenient for customers to visit. For redundant products in the sample room, neatly placed at the bottom of the display table.
Improve the warehouse management network system, standardize the management of warehouse entry and exit, and improve the accuracy of data.
we established the data records of the incoming and outgoing, and carried out the corresponding verification work for each completed document.
Before counting the data, we need to make a plan. In very special cases, detailed records are needed. At the same time, goods on the warehouse need to be standardized to avoid the occurrence of leakage, mistake and other phenomena.
Orders issued by customers, whether from the system or from people, must ensure the smooth acceptance of orders, and constantly improve the processing speed of orders.
This link requires warehousing officers to communicate with the staff of other departments. Inventory turnover requires the warehouse keepers to understand the characteristics of the product, the pressure of the goods in the warehouse, and the understanding of the pre-purchase period, including (sales, finance) and so on.

Quality control, which is defined as "the general name of relevant personnel for operation technology and activities,product quality inspection,analysis, improvement and non-conforming product control after quality problems are found to meet the quality requirements."
Quality assurance ,which is defined as "all planned and systematic activities implemented in the quality management system and verified as required to provide sufficient trust to show that the entity can meet the quality requirements."
QC is the operation technology and activity to make products meet the quality requirements, including inspection, correction and feedback.
For example, QC will eliminate the defective products after inspection, and then feedback the defective information to relevant departments for improvement measures. Therefore, the control scope of QC is mainly in the factory. Its purpose is to prevent the input, transfer and delivery of unqualified products, to ensure that the products meet the quality requirements and only qualified products can be delivered to customers.
The purpose of QA is not to ensure product quality, but to provide assurance. Therefore, it is necessary to manage the whole process from understanding customer requirements to after-sales service, which requires the enterprise to establish a quality control system, formulate corresponding documents to regulate the activities of each process and leave evidence for the implementation of activities, so as to provide trust.
Inspection before unloading. Before the raw materials are unloaded at the factory, the quantity shall be counted first, and the external packing shall be checked to see if there is any damage, oil stain, moisture, etc. Make sure everything is in good condition before unloading.
Warehouse in allocation and sub inspection, place raw materials in specific positions according to different materials, and record relevant data.
Test before production line , remove the outer packaging, cut off the head material, check the surface coating of raw materials.
During on-line operation, the quality inspector shall observe whether there are serious indentations, scratches and other conditions on the surface of the product at any time.If the product does not meet the quality requirements, it shall be placed separately. To the size of the test using sampling inspection, measuring the product's outer diameter, inner diameter, countersunk height and so on.
The quality inspection personnel carry out spot check on the product size, and observe the coating on the surface and whether there are rust spots, oil stains, glue injection and sealing of the rubber strip.
Before warehousing, the quality inspection personnel carry out batch inspection on the products, and those with obvious damage and non-compliance are classified as defective products, those without scratch damage on the surface are classified as class A, and those with slight scratch are classified as class B.
After the production of a batch of products, carry out spot check.
Here we usually use drop test, air tightness test and hydrostatic test.
Drop test:
According to the international UN standard, three tests are conducted. When the specific gravity of the container does not exceed 1.2, the drop height is 1.8m, 1.2m, 0.8m respectively. When the specific gravity of the container exceeds 1.2, the drop height is d*1.5m, d*1.0, d*0.67M respectively. D refers to the density specific gravity of the transported goods.
The criterion of qualification is that there is no leakage when the internal and external pressure reaches balance.
Air tightness test:
Conduct three tests, the pressure in the container is not less than 30KPa, not less than 20KPa and not less than 20KPa.
Hydrostatic test:
Conduct three tests, the pressure in the container is 250kPa, * 100KPA, * 100KPA respectively.
The basis for judging qualified is to keep no leakage for 5 minutes under the specified pressure.
Pre shipment inspection: before shipment, the products shall be inspected in our factory to confirm the quality of the goods.
The scope of inspection includes quality, quantity, package, mark and supervision. Check whether the size of the goods meets the requirements, and check whether the surface is scratched, greasy dirt, peeling off, etc. Whether the packaging is suitable for export transportation, and whether the product will be damaged by such packaging.
There are three inspection methods: customer inspection, third party inspection and factory inspection.
Customer inspection: before delivery, the buyer will send quality inspectors to our factory to check the quality and quantity of the products, and then deliver the products if they meet the requirements.
Third party inspection: it refers to the commodity conformity inspection and approval activities carried out by an independent third party (such as full-time supervision and inspection institution) outside the interests of the buyer and the seller, in an impartial, fair and authoritative non party capacity, in accordance with the relevant laws, standards, contracts and other basis recognized by both parties.
Factory inspection: our factory carries out various inspections on the goods before delivery.
Usually, when the customer can not come to the factory for inspection, we will carry out spot check on the goods at the packing site, and show the products to the customer through photos and videos.
The main tools used for bottom and lid inspection are depth gauge and vernier caliper.
The buried depth shall be measured with a depth gauge.
The outer height, inner height, inner diameter dimension and outer diameter dimension of the lid,the width and thickness of rubber strip, the thickness of bottom edge, and the outer diameter and inner diameter of the round edge are measured with vernier caliper. The scratch, luster of lid and bottom are all tested by visual inspection.
cup crown test:
Before entering the factory, the raw materials shall be sampled for inspection, and the destroy cup crown test shall be conducted to observe whether there is membrane breaking or separation from the base material. After forming, the destroy cup crown test is carried out again to observe whether there is membrane breaking or separation from the substrate.
Acid and alkali brine test of finished product (sodium hydroxide+industrial salt): Soak the bottom and lid of laminated steel in acid and alkali brine for 24 hours, test the corrosion resistance, observe the chemical reaction of PET film on iron and oil, and observe whether there is rust, blistering or black spot.
Acid and alkali brine test (sodium hydroxide+industrial salt): before raw materials entering the factory:cut a section of laminated steel soaked in acid and alkali brine for 24 hours, test the corrosion resistance, observe the chemical reaction of PET film on iron and oil, and observe whether there is rust, blistering or black spot.
Solvent resistance of EVA sealing ring test (butanone toluene): Soak the EVA sealing ring in solvents such as butanone and toluene for 24 hours to observe if there is any change in the EVA sealing ring and test its chemical stability.
Immersion test: Soak the bottom and lid in the oil for 24 hours to see if the oil corrodes the PET film and rubber strip.
Solvent resistance test of finished products: Soak the bottom and lid of laminated steel in 20% and 40% toluene for 7 days respectively, and observe whether there are blistering, film removal and other phenomena.
