In aluminum production, measurement tools for inspectors as their weapons. If the weapon is semi-paralyzed or damage to state that the test results would not make any sense, but there is no supervision of product quality control role. Therefore, measuring the maintenance and care is very important. Here are a few measurement tool maintenance specifications (for commonly used detection tool):
1 Measuring exhausted after, to clean surface stains, Aluminum Strip, loosen the fastening device, when the long-term (one month or more) when not in the measurement surface to be oiled. Gage when not, to put it in a protective case, it is best to use someone full-time, and do measuring unit testing by the authoritative annual record.
(2) Do not use the caliper jaws as the stylus tip, compasses, or other tools, are not allowed to artificially twist two jaws or to gauge when the card board uses.
3 Do not oil stone, emery cloth and rub the surface of measuring surface and measuring reticle part non-metering maintenance personnel, non-demolition, alteration and unauthorized repairs gauges.
4 Do not touch the gage measuring surface, because the hands have sweat and other dirt can contaminate the measuring surface, making it rust. Measuring do with other tools, and metal substances mixed together so as not to bruise measuring tools.
5 gage storage place should be kept clean, dry, no vibration, no corrosive gas, and to stay away from a large range of temperature change place or places where magnetic fields. Storage box measuring gages to clean and dry, are not allowed to store other debris.
6, when the surface has burrs, must go to the net burr, and then measure, or make measuring wear, and will affect the measurement accuracy of the results.

Classification of aluminum alloys
Cast Aluminum Alloys can be classified according to chemical composition of Al-Si alloys, aluminum-copper alloys, magnesium alloys and aluminum-zinc alloy. A pure aluminum products aluminum smelting products and pressure processed sub categories, the former chemical composition Al said the latter with pinyin LG (aluminum, industrial use) expressed. Second, the pressure processing aluminum alloy pressure processing products into rust (LF), hard (LY), forging (LD), hard (LC), coated (LB), special (LT) and the solder ( LQ) and other seven categories. State of the aluminum alloy material used annealing (M annealing), hardened (Y), hot (R), three. Third, aluminum and aluminum alloy processed into a certain shape of the material referred to aluminum, including plate, strip, foil, tubes, rods, wire, type. Fourth, cast aluminum cast aluminum alloy (ZL) by components outside the main elements of aluminum silicon, copper, magnesium, zinc divided into four categories, namely 100,200,300,400 code encoding. Five, high-strength aluminum alloy high strength aluminum alloy means a tensile strength greater than 480 MPa aluminum, primarily in hard aluminum alloy pressure processing class, hard aluminum alloy casting classes and categories.
Quality aluminum alloy material identification methods
First: the use of materials
Aluminum windows and doors main timber generally include three aspects: aluminum, glass, metal pieces, the owners buy products, they often pay more attention to the thickness of aluminum and glass, while the hardware requirements are not very high, it is not comprehensive. In fact, the state requirements for aluminum windows and doors there is a certain standard. High-quality aluminum alloy doors and windows used, its thickness, strength, and the oxide film can generally in line with national standards, such as relevant state requirements: aluminum windows and doors Aluminum Alloys wall thickness shall be not less than 1.2mm, the oxide film thickness of 10 microns. The tempered glass is better than ordinary glass, doors and windows if to consider safety and durability, stainless steel metal parts (such as screws, hinges, handles, etc.) than the aluminum parts is good, but the best choice pulley products using POM material because such products have higher strength and wear resistance, use the process smooth, non-perishable. You know, usually from doors and windows broken window fittings started yo!
Second: Processing
With good material, the next step is the processing of the doors and windows. Because aluminum windows and doors the technical content is not high, the current is not high degree of mechanization, the majority of workers are also dependent on the installation manual, which requires operators to have a good awareness of product quality. In the production process to enhance the operator's proficiency and product awareness is very important. High-quality aluminum windows and doors, fine processing, tangent smooth, consistent angle (main frame material under normal circumstances is 45 degrees or 90 degrees), in the splicing process should not appear obvious gap, good sealing performance, switching smoothly. Poor quality aluminum windows and doors, especially if machining aluminum outdoor window products fail, there will be sealed nature of problems, not only leakage leaking, but also in the strong winds and large external force, the glass will be burst, shedding phenomenon, giving cause losses of property owners and even wounding phenomenon.
Third: Appearance
Owners buy aluminum doors and windows products, usually very focused on the product's appearance and glass decorative patterns, but often underestimate the surface of aluminum windows and doors composite membrane, the composite membrane is an artificial coloring oxide film formation, corrosion resistant, wear-resistant loss, high gloss, but also has a certain fire safety features, so buy more aluminum doors and windows products should compare similar products. Art on the glaziers varies with different owners to choose according to their preferences.
Fourth: Price
Since the level of prices and aluminum windows and doors aluminum price level has a direct correlation, but in general the performance of aluminum windows and doors in a given period the price is relatively stable, in general, than the price of inferior quality aluminum alloy 30% higher windows and doors, aluminum windows and doors usually inferior contains a lot of impurities in recycled aluminum extruded aluminum, the use of aluminum and some only 0.6-0.8 mm wall thickness, either from the tensile strength or yield degrees are greatly below the national regulations, such aluminum alloy doors and windows, especially aluminum outdoor window is very safe, so the owners do not buy products cheaper and despise momentary own personal safety and that of others.

Insulated aluminum processing technology classification
Insulated aluminum processing technology can be divided according to two categories: embedded and dispensing roll style. At present, there is no corresponding standard insulation aluminum in Europe insulation systems generally use mass of technology, North America and Korea perform AAMA TIR-A8-90 plastic injection-type Aluminum Alloys structure building insulation performance specifications. Our bridge insulated walls and windows and doors in both the pass there dispensing strip style.
(1) Rolling embedded
Is dedicated heat insulation aluminum doors and windows, inside and outside the two aluminum insert special notch, through special machinery rolling, leaving the insulation strip fused with internal and external profiles, this approach in European countries, especially Germany and Italy, Central European countries generally adopted.
(2) dispensing formula
The basic principle is to treat aluminum alloy into two parts between the two using a specially formulated polymer insulating polymer eleven off hot glue to combine. Thus, one hundred aluminum alloy is formed between the inner and outer part of the effective heat insulation layer, so that through the door window frame profiles or fan heat dissipation pathway is blocked, to achieve energy-efficient insulation purposes.
