Reflective glass is clear or tinted glass that has a very thin layer of metal or metallic oxide on the surface. The reflective coating is applied during the float process. The thicker the glass is, the less light will pass through the window. The reflective coating reduces heat gain and glare from the outside while allowing visible light to enter. Toughened Reflective can be used directly, and also can be processed into Laminated Glass, Insulated Glass for windows, doors, building walls and so on.
Tempered Glass is often used in applications where using standard glass could pose a potential danger. Tempered glass is stronger than standard glass and does not shatter into large shards when broken. This is important, because it can greatly minimize potential danger in the case of a break. Manufactured through a process of extreme heating and rapid cooling, tempered glass is much harder than normal glass.
In the case that tempered glass does break, it shatters into small pebbles that are void of dangerous, sharp edges. As tempered glass is considered to be much safer than normal glass, you may often here it referred to as safety glass or TOUGHENED GLASS . Tempered glass has a wide variety of uses that you'll find just about everywhere. In fact, the shower doors in your bathroom or the side glass on a motor vehicle are examples of tempered glass.
Annealed float glass mainly clear float glass, ultra clear float glass, color tinted glass, reflective glass, they are substrate, can be processed into tempered glass, laminated glass, insulated glass, LOW-E glass, Frosted Glass , Back Painted Glass, Printed Glass , coated glass. Tinted reflective glass mainly brown, grey, blue, green. It can be processed into colored reflective tempered glass, Reflective tempered laminated glass, Reflective Insulated Glass and so on on customer's request.

First, the classification of raw materials and suppliers of evaluation and selection 1. The production of raw materials should be classified management, highlighting the need for key hardware companies, a wide range of raw materials, but different raw materials have different effects on the quality of production products. In order to facilitate the control of procurement quality, the raw materials should be categorized and managed according to the degree of influence of the raw materials on the quality of the products. Generally divided into three categories:
A type of raw materials: refers to the production and use process, which may have a direct and significant impact on product quality (such as may have a direct impact on the key functions and performance of the product).
Class B raw materials: refers to the production and use process, which may bring indirect or more important impact on the quality of raw materials.
C-type raw materials: refers to the general auxiliary parts, the impact of the general or slight raw material quality.
2. The evaluation of raw material suppliers shows that whether the quality of raw materials purchased is stable depends largely on the quality management of suppliers. Therefore, the quality assurance ability of various raw material suppliers should be evaluated before procurement.
(1) Appraisal of suppliers of Class A raw materials The focus of evaluation of suppliers of Class A raw materials is generally to conduct on-site inspections and evaluations of the operating conditions of their quality systems, past availability, handling and rectification capabilities when supply quality is abnormal, and on-time delivery. And the number of delivery capacity, its cost performance, its after-sales service capabilities (including after-sales service attitude, timeliness, effectiveness). At the same time, it is also necessary to review the supplier's data, investigate and understand the suppliers' other customers, test and provide samples of raw materials, and provide regular analysis of raw material quality.
(2) Evaluation of B and C raw material suppliers.
Generally do not visit the site, mainly consult the suppliers to provide information, to provide samples of raw materials for testing trials, analysis of the results of regular analysis of the quality of raw materials, etc., to achieve the evaluation of suppliers. Its: For B grade raw material suppliers' evaluation, the Procurement Department puts forward the "B-type Raw Material Supplier Appraisal List" to provide B-type supplier related data, or previous B-type raw material inspection, usage, etc. Quality, service, price, and other information and information , send relevant technology, manufacturing, quality, finance and other relevant departments to sign (accreditation), and report to the top management for approval; for the evaluation of the ability of the class C raw material supplier, the procurement department puts forward the “C class supplier evaluation list†by quality, After the signing of the financial affairs and the signing of the purchasing department manager, they will be executed.
3. Selection and determination of raw material suppliers The supplier of qualified raw materials should be determined through selection. Obtaining a qualified raw material supplier depends on the above-mentioned factors such as the evaluation results of each supplier's quality assurance ability, production and use conditions, prices, and credit. Therefore, to finalize the supplier, several suppliers of the same kind of raw materials should be appropriately selected for comparison, in particular, the production and use conditions and the quality assurance capabilities of all suppliers are basically equivalent.
2. Strict control of raw materials entering the factory Purchasing raw materials from qualified suppliers is not always a good thing. The qualification of the supplier only indicates that the supplier has the basic conditions for providing relatively stable quality of raw materials, whether the actual quantity of raw materials received is in short supply, and whether the quality can meet the production requirements is still not certain. Therefore, before entering the factory, the raw materials should also strictly comply with the following requirements to ensure good quality of the factory.
1. There is no need to check raw material acceptance. Should be based on raw material procurement contract, with the counterparty "certificate", "Material" and other quality certification materials acceptance; for individual low-value consumables and difficult to issue the corresponding "certificate", "Material", must be provided in advance samples. For raw materials without "certificate" and "material book", acceptance and storage shall be rejected.
2. For the need to test the raw materials after passing inspection before storage. Before inspecting raw materials for storage, the purchasing department shall fill in the “Send Inspection Record†and submit it to the professional inspection department. After the professional inspection department issues the qualified inspection report, it will be put in the warehouse according to the qualified report. If the inspection fails, you should fill out the "Rejected Product Record" form and fill in the quality information feedback one-time quality competent department feedback, request the procurement department to handle the return and replacement procedures.
3. Establish timely acceptance records after checking the income database. The custodian shall establish a Record of Acceptance of Raw Material Receipts. The record shall include: raw material name, specification, model, manufacturer, arrival time, arrival quantity, qualified quantity, acceptance time and corresponding quality certificate; and according to the material type, name, Specifications are posted separately for the purpose of future enquiries and confirmations.
4. The raw materials used for emergency or quality certification are not fully accepted. For materials that are urgently used or quality certification materials are not complete, one-time quality feedback department shall fill in the information quality feedback. The quality management department shall urge the procurement department to submit the quality certification materials, and store the raw materials according to the acceptance inspection procedures. If you fail to qualify, you can go through the acceptance procedure after you have verified the quality.
5. Acceptance quality of materials Appearance of raw materials should be inspected for damage and defects, and see if there is any corrosion or leakage in the packaging. Check the product name, grade, specification, etc., by unpacking, and pass the product qualification certificate and packing list acceptance.
6. For the internal quality problems that can only be revealed during the installation and use phase, the raw material custodian should establish a quality tracking card, keep in touch with the production and use unit, master the first-hand information, make sure that the problem is found and timely feedback, and notify the supply department to handle according to the regulations. .
Third, strict quality control of incoming raw materials to prevent deterioration of incoming raw materials, raw material procurement process control, the key to do the following management.
1. Manage raw materials for storage. For stocks of raw materials, especially A-type raw materials, they should be inspected frequently to ensure that they do not suffer from tides, corrosion, rust, mildew, rottenness, change, deterioration, frost, damage, or loss. .
2. Treasury environmental management. The shelves and articles in the warehouse should be arranged reasonably, the passages should be smooth, and the doors and windows should be free of damage. The “three nets†(ground, doors, windows, and shelves) should be provided, and there should be no sundries, garbage, and dust.
3. Warehouse raw material stacking and covering. Stacking cover also ensures that the library has an important aspect of raw material quality. Inventory raw materials must be properly stacked and covered according to their performance and storage requirements. Special consideration should be given to the performance of Class A raw materials, the quality of packaging, and the ground conditions of the warehouse, and appropriate methods of palletizing should be adopted to achieve flood prevention and moisture protection.
4. Check raw materials. When raw materials enter the warehouse, inspection and palletizing shall be carried out in accordance with the requirements for classification and maintenance of raw materials. Regular or regular inspections shall be conducted to eliminate and deal with hidden dangers in time.
5. Raw material delivery management. The principle of "first-in, first-out" should be followed, and in particular, the long storage period, large stockpiles, difficulty in checking raw materials, and the timely release of such raw materials should be required. At the same time, standardize the storage process behavior to avoid the damage caused by the handling process to the quality of raw materials.
Fourth, the quality of raw material procurement Regular analysis of the quality of raw material procurement analysis, many metal mold companies easy to ignore, but very important part. Regular analysis of the quality of raw material purchases can be used to determine whether suppliers have a regular supply of raw materials with stable quality, and provide important information or even evidence for supplier selection and adjustment after the next step in the production process quality control.
Regular analysis of the quality of raw material purchases shall be carried out. Type A raw materials shall be carried out once a month. Type B raw materials shall be conducted once every six months. Type C raw materials shall be conducted once a year. The main contents of the analysis are: statistical analysis of the acceptance results of trials of raw materials, testing, etc.; status of delivery and delivery of suppliers as scheduled; processing and rectification of abnormal supply quality.
In short, metal mold enterprises not only pay attention to the production process, pay attention to efficiency, but should pay more attention to the quality of raw material procurement. Do a good job in the quality management of raw materials for procurement, and strengthen the quality control of the procurement process, so that product quality can be reliably guaranteed on a solid basis.
How Mould Enterprises Can Turn Off Quality of Raw Materials
Raw materials are crucial to the production of hardware and die products and guarantee the quality of hardware and die products. However, with the increasingly fierce competition in the hardware material market, there are always some profit-making manufacturers or unscrupulous traders who will bring counterfeit and inferior products to the market. Even if some regular manufacturers, due to their own management loopholes or other reasons, may also allow some inferior products to flow into the market. market. The production process of these counterfeit and inferior products constitutes a major quality or safety hazard, and has become the culprit for product quality accidents or accidents. In addition, if the procurement of raw materials is not properly controlled, it will also directly affect the quality of production. How to prevent counterfeit or deteriorating raw materials from flowing into the production line is a task for each mold company. Luo Baihui, an industry expert, believes that metal mold companies must control the quality of raw material procurement and ensure product quality and safety. They need to be controlled from the perspectives of raw material suppliers' evaluation and selection, strengthening the acceptance of raw materials before they are put into storage, and improving the quality of warehouse management.
