Tips and methods for purchasing imitation copper doors:
1. Check the performance and structure of the door lock:
The anti-drill lock is selected. After the drill bit is drilled into the lock hole, the lock will rotate synchronously with the drill bit when rotating, which can play the role of the lock without being damaged. The lock requires a three-way locking structure, three hinges for single door opening, six hinges for double door opening, and a door lock for the door leaf and the door frame. Even if the hinge is broken, the door cannot be opened.
2. Look at the number of locks on the door and the number of inserts:
It is best to choose two locks to control the door of each of the two plungers, even if it can be destroyed, it will delay the time. Generally speaking, a lock can control 3 to 4 plungers. Such a door has poor anti-theft performance. Once the lock is damaged, several plungers lose their effect at the same time.
3. Look at the thickness and area of ​​the stiffener around the lock:
The copper door is divided into two types: closed type and fence type. Regardless of which one is chosen, the lock is the main part of the theft damage. Therefore, the lock core plate should be a cold steel plate with a thickness of more than 2 mm. The height of the core plate is not Less than 500 mm.
4. See how the process quality is:
The choice of imitation copper door materials is fundamental, and the quality of the production process is the key. In particular, attention should be paid to the presence or absence of weld defects such as open welding, unwelded welding, missing welding, and slag inclusion. Check whether the cooperation between the door leaf and the door frame is dense, whether the gap is uniform, whether the opening is flexible, whether all the joints are foraging, whether the paint plating is uniform, firm and smooth.
5. Pick from the design:
The imitation copper door on the market is divided into three categories: luxury, mid-range and ordinary. The luxurious panel material is stainless steel plate, the main frame is made of stainless steel square tube, the flower decoration fence is made of stainless steel profile; the mid-range type is generally combined with square round steel and floral decoration; the common type is square steel tube, round steel and flat steel ( 16 × 4 mm) and other materials. Users can choose their favorite type according to their own situation.

Advanced Plastic is a polymer material which has a higher comprehensive performance and can be use in long-term temperature above 150 ℃.It is mainly used in the field of high technology .So we also call it as the high performance engineering plastics or heat resistant engineering plastics.
This kind of material has excellent characteristics of light weight, high strength , good heat resistance and others and its application is from the original national defense and aerospace to the field of car, equipment, high-end consumer goods and many civilian areas.
There are many kinds of Advanced Plastic produced by Dongguan Noegem Plastic Product Co.,Ltd .
1. Production:
Polyphenylene sulfide plastic sheet (PPS plastic sheet),
PPS plastic which also called Polyphenylene sulfide.On the primary key is extremely dense and sulfur atoms of benzene ring, thermoplastic resin is high rigidity, high crystallinity, have higher strength and modulus, products can be used in the 200 ~ 224 ℃, 250 ℃ under the main performance.
2. Production:
Polyether imide plastic sheet (PEI plastic sheet),
Antistatic polyether imide plastic sheet (ESD PEI plastic sheet),
Conductive polyether imide plastic sheet (CON PEI plastic sheet),
Polyether imide plastic rod (PEI plastic rod),
Antistatic polyether imide plastic rod(ESD PEI plastic rod),
Conductive polyether imide plastic rod (CON PEI plastic rod),
PEI plastic is characterized by high intensity, high rigidity, abrasion resistance and dimension stability.PEI plastic is a transparent solid of amber, which has inherent flame retardancy and low smoke intensity without adding any additives. The oxygen index is 47% and the combustion level is ul94-v-0.
PEI plastic is 1.28 ~ 1.42 g/cm3 density, glass transition temperature is 215 ℃, thermal deformation temperature of 198 ~ 208 ℃, can use for a long time under 160 ~ 180 ℃, allows intermittent maximum temperature of 200 ℃
PEI plastic has excellent mechanical strength, electric insulation, radiation resistance, high and low temperature resistance and fatigue resistance and molding processability;The addition of Glass Fiber, carbon fiber or other filler can enhance the modification purpose.
3. Production:
Polyether ether ketone plastic sheet (PEEK plastic sheet),
Antistatic polyether ether ketone plastic sheet (ESD PEEK plastic sheet),
Conductive polyether ether ketone plastic sheet (CON PEEK plastic sheet),
Polyether ether ketone plastic rod(PEEK plastic rod),
Antistatic polyether ether ketone plastic rod(ESD PEEK plastic rod),
Conductive polyether ether ketone plastic rod (CON PEEK plastic rod),
Polyetheretherketone (PEEK) plastic is a kind of excellent performance of special engineering plastics, has more significant advantages compared with other special engineering plastics..Can be used for high-end technology such as mechanical, nuclear engineering and aviation.
Advantage :
1)Excellent chemical resistance and hydrolysis resistance
2)Excellent physical and mechanical properties
3)Resistance to high temperature is 260 degrees,
4) light and good dimensional stability
5 )excellent flame retardancy
6)Good electrical insulation and electrical stability
7 )it can be mixed, easy to process composite
8)Good self-lubrication
4. Production:
polyphenyl ether plastic sheet(PPO plastic sheet ).
PPO plastic is a special kind of Engineering Plastic, which has many features that other engineering plastics do not have:
1. Transparency: PPO plastic is one of the few transparent plastics;
2. Non-toxic: PPO plastic itself is less toxic and more suitable for food and medical applications;
3. Low temperature resistance: the low temperature of the PPO in the low temperature of minus 170 degrees centigrade, which is a lot of engineering plastic;
4. Low gravity: 1.08 g/cubic cm is slightly more dense than water;
Main features of Advanced Plastic
Heat temperature of 150 ~ 300 ℃
Advantages :
1).Good in heat resistance,
2).Good chemical resistance and radiation performance,
3).Good flame retardancy
4).Good stiffness, strength, toughness, creep, abrasion and other comprehensive mechanical properties.
Application: space aviation, defense military industry, nuclear power, electronics, transportation, machinery manufacturing, medical devices and other civil fields.
