1. 导热塑料的RoHS, UL 认证

是否具备 RoHS, UL 认证,对出口欧洲、北美市场的整灯工厂,将是非常关键的因素。而RoHS, UL 证书的颁发机构,事实上也对材料做了一个初步的筛选工作,这对很多厂家来说,在不太熟悉导热塑料这种新材料的情况下,可以通过检测机构的认证来更多了解导热塑料。值得注意的是,UL认证编号是可以通过网络进行查询,其真实性是比较可信的。
 
Whether it has RoHS, UL certification, export to Europe, the North American market, the whole lamp factory, will be a very key factor. And RoHS, UL certification authority, in fact, also made a preliminary screening of the material, which is for many manufacturers, in the case of the new material is not too familiar with the heat conduction, can be more understanding of the thermal conductivity of plastic. It is worth noting that the UL authentication code can be queried through the network, its authenticity is more credible.

济南大型围挡 http://www.gift4yu.com/ 导热塑料的料性有热塑性和热固性之分。绝大多数的导热塑料是热塑性原料,这样的材料可用传统的普通注塑机生产,如果是原来做节能灯的厂家本身拥有大量的注塑机,可以继续沿用下去。另外一种习惯做法是,把注塑环节外包给专业注塑公司,在自有生产能力不足的情况下,可以轻松借道外协厂扩大产能。
 
The material properties of the large enclosed heat conduction plastic in Ji'nan are divided into thermoplastic and thermosetting. The vast majority of the thermal conductive plastics is thermoplastic raw materials, such as the use of traditional ordinary injection molding machine production, if it is the original manufacturers of energy-saving lamps have a large number of injection molding machine, can continue to use. Another common practice is that the injection aspects of outsourcing to professional injection molding company, in its own production capacity is insufficient, can be easily route through outsourcing factory to expand production capacity.
 
反之,如果导热塑料为类似酚醛树脂的热固性材料,将不能使用普通注塑机,必须使用专用热固型塑料注塑机,额外的设备费用将会大大增加成本。而且一旦自有注塑产能不足,比较难找到合适的外协注塑厂。
 
Conversely, if conductive plastic like phenolic resin thermosetting material, can not use ordinary injection molding machine, must use special thermosetting plastic injection molding machine, additional cost of equipment will greatly increase the cost. And once its own injection capacity is insufficient, it is difficult to find a suitable external injection molding plant.
 
从实际操作来看,热塑性材料的成型周期要比热固性材料短,这也意味加工成本会有所降低。
 
From a practical point of view, thermoplastic material molding cycle is shorter than thermosetting material, it also means that the processing cost will be reduced.
 
3. 材料的颜色

通常导热塑料中是一定的基材(比如PC,PPS, PA)基础上添加助剂合成的,这些导热助剂通常是深色材料,而最终的客户需求通常是以白色为主,如果不能提供合格的白色原料,可能导致注塑成型后多加一道喷漆工艺,从而增加成本支出。
 
Usually heat conduction plastic is a certain substrate (such as PPS, PC, PA) based on the addition of additives, these heat conductive additives are usually dark material, and the final customer demand is usually based on white, if you can not provide qualified white raw material, may lead to injection molding process more than one spray, so as to increase the cost of expenditure.
 
4. 原料的生产地

以目前的LED整灯出口订单来讲,交货期会是重要的条款。如果导热塑料是在国内生产,交货应有足够应对时间。而原产地为境外,通常要考虑海运及通关进口环节,交货时间会有延长,同时进口原料的销售成本也会比同样在国内产地有所上升。
 
In the current LED entire light export orders, delivery will be an important clause. If heat conduction plastic is in domestic production, delivery should have enough time to deal with. And the origin of overseas, usually to consider the import of marine and customs clearance, delivery time will be extended, while the cost of imports of raw materials will also be higher than the same domestic production.
