This head is 50mm-200mm suitable for product initial diameter.
The beneficial effects of the utility model are：
1 the technical program is my company according to Canadian advanced technology, absorb and transform produce be more suitable for state
Interior to use head, be particularly suitable for use in more than seven layers of various functions film of this product is manufactured.
2 this products are made up of more than five groups parts, then select more than five extruders, are assembled into complete head, each portion
Part is made up of three parts（Each one of bolster, conveyor screw one）, installation is carried out according to certain angle during assembling,
3 the technical program can control the temperature of individual layer respectively, so as to improve equipment because every layer is separate feeds
Overall processing precision.
4 the technical program are overlaying structure, the quantity that can set single layer structure according to being actually needed, enhance equipment
Applicability.
The handpiece structure of 5 our company design, overcomes the heaviness of traditional Die Design, complicated, not easy processing, uses
The shortcomings of family is not easy to assemble, and cost is too high, this product is simple in construction, easily fabricated, fault rate is low, safe and reliable, energy-conserving and environment-protective,
It is easy to operation.
