傳統(tǒng)的納米注塑，需要進(jìn)行表面處理，同時(shí)對金屬，塑料性能，模具結(jié)構(gòu)，注塑參數(shù)有很高的要求。日本寶理開發(fā)了一種Quick-10 技術(shù)，無需表面處理即可讓塑料和金屬有效的連接一起，這種技術(shù)利用對金屬嵌件快速的升溫和降溫，僅在注塑過程中就能夠完成塑膠和金屬的粘接。寶理已經(jīng)開發(fā)可以用于Quick-10 技術(shù)的PBT，和PPS。
Engineering thermoplastics supplier Polyplastics has developed a technology that improves metal-plastic bonding of composite parts for the automotive and electrical/electronics industries without the need for pre-treatment of the metal inserts.
Polyplastics’ Quick-10 metal-plastic bonding technology has been used in mobile device parts (mobile phones, tablets, digital cameras) and some auto-related parts.
Direct metal-plastic bonding is a process which typically employs metal insert molding. In the traditional process, metal inserts and plastics are firmly bonded via introduction of molten plastic through injection molding to metal inserts which have already undergone appropriate surface treatment. These metal-plastic composites combine the properties of metals (high rigidity, electrical conductivity) and engineering plastics (low density, electrical insulation). However, while numerous factors (metal inserts, plastics, mold structure, injection molding parameters, etc.) generally have adverse effects and prevent stable bonding, Polyplastics has made progress with successful bonding through its Quick-10 technology.
The Quick-10 process usesrapid heating and cooling of metal inserts to realize direct metal-plastic bonding through the injection molding process alone, without any special surface treatment for the metal.The plastics employed must, however exhibit properties such as interface affinity, surface transferability (flowability), and low shrinkage to realize good bonding. To this end, Polyplastics has developed appropriate polyphenylene sulfide (PPS) and polybutylene terephthalate (PBT) grades for the process

補(bǔ)充資料：
日本大成塑料（Taiseiplas）株式會(huì)社于2002年發(fā)明了納米成型技術(shù)（NMT）。大成第一個(gè)字母為T，所以命名T處理。我國研究人員改變了納米孔形成方式，衍生了不同的處理方法，其中，在通電的情況下進(jìn)行的處理方法被稱為E處理，字母E是電的縮寫
