Abstract
A process of manufacturing the main body of a bike helmet includes the following steps: (I.) coating with a base layer resin: that is, uniformly coating the entire shock absorbing liner with a base layer resin; (II.) coating with a protective layer resin: uniformly coating the base layer resin with a protective layer resin to form a shell; (III.) transferring pattern: transferring the pattern to print on the shell; and (IV.) clear coating: spraying clear coating on the pattern. By the aforesaid steps of the process, the shock absorbing liner and the shell are able to join tightly, which solidifies the helmet for better durability, to prolong the years of use, to substantially lower the production cost, and to boost the yield rate.
Claims5
A process of manufacturing a main body of a bike helmet comprising:
- (I.) entirely uniformly coating an outer side of a shock absorbing liner by spraying with a reciprocating pump with a base layer resin and hardening under room temperature;
- (II.) uniformly coating the hardened base layer resin by spraying with a gravity-type handheld spray gun with a protective layer resin, setting aside, and then heating at a temperature of 50° C. to form a shell;
- (III.) transferring a pattern to print on the shell;
- and
- (IV.) spraying the pattern printed on the shell with clear coating.
