8. Bakelite is a thermoset material, so once melted and hardened it is not possible to melt it again in case  of wastage or damage  of knob, it is having the best application where heating of product is done in use. But in most of application like machine lever handle knob heat is not applied in used and damage of knob in use is another big problem. Hence unnecessary non recyclable wastage is produced. This can be reduced by changing the material of ball knob by Nylon-6 which is having higher impact strength and easily recyclable.  VI. Future Scope  1.  In manual injection molding of machine tool handle lever knob it was found that rejection rate was 8% due to various defect which is higher than 5% of compression molding. The rejection rate can reduced by application of automatic machine. 2.  In manual injection molding of handle lever knob the down time was 60 second which is higher than that of 50 sec in compression molding. This can be reduced by application of automatic machine with multi cavity die. 3. This research was carried out in small scale industry with single cavity die and manual injection molding machine. So human element was play vital role. If automation was applied in plastic product manufacturing industry than productivity may further increased and hence cost of product can further decreased.    4. The cost of knob can further reduced by using recycled nylon-6 material.    VII. References i.  “Plastics Engineering, Manufacturing & Data Handbook”, edited by Dominick V. Rosato, Nick R.

材料和生产工艺的变化对塑料制品的生产周期、生产速度、成本和冲击强度的影响

翻译后摘要:在本研究论文中,塑料制品的材料变化的影响进行了研究,观察到的参数是废物回收,产品的影响性能,美观的外观,周期时间,生产速度和产品的成本。在这项研究中发现,通过产品材料为热塑性塑料和热固性塑料的生产从压缩成型注射成型过程的变化,因为热塑性材料是可回收利用的产品成为生态友好。还发现,冲击强度和生产速度/小时也有改善,由于减少周期时间。美学外观:产品表面光滑、外观光滑、持久。最终产品的成本大幅降低。在一个小规模的行业进行了研究,与机械工具手柄杆球旋钮的案例研究。 塑料制品模具设计英文文献和中文翻译(3):http://www.youerw.com/fanyi/lunwen_50469.html
