the difference between the external light and the injection molding process.
Full-color series products because of its production process is relatively complex and on-site installation and after-sales service is such complicated reasons, caused the market at present about tiger color for full-color series products, many manufacturers also avoided in full color products. However, some enterprises have formed their own production process because of years of production experience. Now commonly used in injection molding process such as the market and the glue process, judge the stand or fall of these two kinds of process, need from the manufacturer's technical strength, and not to point with the said a kind of technology that is good or bad.
Injection molding process lamp string grouting process lamp string.
1. Material use is different.
Injection molding process is mainly to pass the injection molding, the appearance is more beautiful, need injection molding machine and other equipment, suitable for mass production. The adhesive process can be used for the common external casing, so as long as the welding lamp is inserted into the PVC shell, it can be injected with the needle tube, and the injection molding machine is not required, which is suitable for small-scale production.
The production process is different.
Injection molding process is mainly through high temperature injection molding, the requirement of lamp bead, IC and related components is higher, especially some lights, after high temperature can appear color blindness, IC will fail, so the poor quality of high failure rate of components. The gluing process does not require high temperature production, only the glue can be injected, the damage to the components is small, and the quality requirements of the components are not high.
3. Different application environment.
Because the full color series products are generally used in high-end customers, the quality requirements are high, otherwise, high maintenance costs are required. Therefore, quality management and maintenance are important indicators for manufacturers. The product's effect, life, construction, maintenance and other strict requirements. There is also a large technology mature manufacturers whether the injection molding process or the quality of the process is good, small workshop no matter what process is not good.
Iv. Technical content determines quality.
The epoxy resin glue glue process a lot of application, this glue what quality is good and evil people mixed up on the market, the key is the rigidity of yellowing and glue, and anti-aging, uv resistance, low resistance to cold resistance to high temperature and other requirements need to have certain technical support. At present, many small workshops simply imitate and copy, and the production process is simple and can be produced at any time. Because of the competition and the use of low price components, so that the product in the use of the high rate of bad, resulting in a poor quality of the adhesive process.
The injection molding process is still more mature, they have their own technical requirements. Like our company's full color series products, after 10 years of long-term production and experience summary. First, we use machine welding lamp to reduce the defective rate; Secondly, we adopt 3 waterproof process: the circuit board is completely waterproof, which can eliminate the moisture infiltration element of the glue material; IC lamp feet secondary waterproofing treatment -- let IC and components have free shrinkage and heat dissipation space; The finished product is made of glue and water-repellent treatment -- -use no glue, even if it is 20 to 30 degrees below zero, the lamp glue will be pulled at room temperature to achieve the purpose of waterproof. Third, the use of the original plant element high temperature injection molding -- the product after the high temperature aging in addition to some of the hidden trouble. The fourth and 24 hour analog application access control system high and low pressure impact aging - ensure low rate of failure in practical application. Fifth, the professional team will provide you with animation design plan, construction plan, maintenance plan; Vi. After-sales service and technical support for the products.
Circuit board comprehensive waterproof treatment IC lamp foot secondary waterproofing treatment finished product line waterproof treatment.
5. Strength and experience of the manufacturer.
Full-color series products don't like to buy Chinese cabbage, he needs more technical service, whether you want to use the glue process or injection molding process, can have a knowledge of the manufacturer first, first to see if the company's related information registered company, can enter the company name shenzhen credit http://www.szcredit.com.cn can understand the company overall situation. Second, check the company's related product testing report and certification. Some companies also simulate UV aging experiments with ultraviolet light. Common aging is mainly light aging, humid heat aging and hot air aging.
6. How to judge the quality of all colored lights?
1, see appearance: injection molding and pouring JiaoGong technique is PVC plastic shell, visible light of PVC plastic sleeve if elasticity is not good, transparency is not high, it is possible to put material floolwing reuse or bad quality of PVC. The better shell can protect against uv, flame retardant, antifreeze and heat resistance.
2, see the glue: glue process to fill the glue to demand higher, whatever process are required to do PCB and IC light foot waterproof and protection, the myth thought since the glue is 100% waterproof, actually a lot of glue is moisture content and harmful substances will cause harm to the element.
3, watch waterproof: injection can see into the first outlet shut if have glue, and then peel the skin look PCB and IC lights outside foot have glue coverage, then you can determine whether the lamp string do waterproof and waterproof quality. What depends on filling glue, glue with hard plastic reflect the yellowing and original in cold and hot prone to adverse changes in the weather is more used soft glue on the market at present, cannot be repaired after construction for cracking.
4, high and low temperature test: the light in the refrigerator frozen layer to 1 to 2 hours, and then light up 1 to 2 hours, can be repeated over and over again, some of the plastic PVC material or glue glue by high and low temperature change will affect the components, or other materials by high and low temperature changes will also be adverse. The glue is easy to separate the shell from the inside of the gel. If the element is not waterproof, it can clearly see the color of the lamp.
5, simulation application field: frozen in the refrigerator to see if good light, the most direct way is to turn the light on the water test, the light can be placed in the water 1 to 2 hours, then take out light 1 to 2 hours, and then pass on 1 to 2 hours to repeat many times, about 2-3 days through the glue and whether to start the yellow light foot.
6. Of course, the quality of the full-color series is influenced by many other factors. Such as lamp bead, IC, wire board, electric wire, colloid, power supply and so on material and production technology and so on the quality of the product concerned.
7, by the above factors can be seen, the LED visible light quality and appearance of the injection molding process and service life are better than the glue process LED visibl。
