制造热塑性塑料摇臂罩的技术自1980年美国开始应用至今已有很大的发展。新的密封方法及铝气缸盖的广泛使用,更有利于发挥热塑性塑料在成本、重量及零件集成性方面的优势, 这些优势是热塑性塑料和注射成型工艺应当具备的。了解了这些发展历史,就可以设计和制造出功能强、重量轻、成本低和有特色的罩盖。 The manufacture of thermoplastic rocker arm cover technology has been greatly developed since the United States began in 1980. The new sealing method and the extensive use of aluminum cylinder heads make it more advantageous to take advantage of thermoplastics in terms of cost, weight and part integration, which are possessed by thermoplastics and injection molding processes. With these history in mind, powerful, lightweight, low-cost and unique covers can be designed and manufactured.
