Blown Film Extrusion Screw Barrel
Blown films extrusion is one of many polymer manufacturing processes. This method is used to produce commodity and specialized polymer films that are typically used in packaging such as shrink, stretch, barrier films (used to protect deli meat), frozen food packaging, and shopping bags.
There are many types of polymers that can be used in blown film extrusion with the most common being polypropylene and polyethylene (LDPE, HDPE and LLDPE). This method can manufacture monolayer films as well as more complex multi-layer films that involve co-extrusion to combine more than one plastic into a single film.
There are several advantages of manufacturing film using the blown film extrusion process including the ability to manipulate the mechanical properties of the final plastic based on the process conditions and base polymer(s) used. For example, blown film extrusion inflates the polymer radially while at the same time drawing the polymer upward with rollers. These forces stretch the polymer in both the transverse and draw directions, providing strength in the film. The extent of inflating and drawing can be adjusted to achieve the desired strength in the transverse and draw directions of the final product. Blown film extrusion is also versatile and able to manufacture a variety of single or multi-layer films with a range of film thickness and width.

Development History
1993 The company "Lichao" was established with the rise of screw industry in China.
1995 Took the lead in introducing CNC machining in the industry.
1997 We firstly started to manufacture alloy bushing barrel, which greatly improved the service life of barrel.
2000 The annual output exceeded RMB 50 million yuan for the first time.
2002 In order to better serve customers, the main plant was relocated to Ningbo.
2003 Jinyi recruited technical talents from Taiwan Province to guide and study alloy casting process.
2005 The centrifugal casting equipment was introduced from Taiwan and put into use.
2007 PTA plasma automatic bimetallic alloy spraying equipment was installed and put into use.
2010 Zhoushan new plant was built.
2011 A new electroplating plant was built in Zhenhai Chemical Industrial Park. So far, all the production processes of Jinyi can be under internal control.
2012 The second factory in Ningbo was built.
2016 The third factory in Ningbo was built, forming a pattern of 2 bases and 5 factory areas in Ningbo and Zhoushan.
2017 "Ningbo Lichao Tie Bar Precision Machinery Co., Ltd." was established, mainly engaged in tiebars manufacturing.
