Our knowledge and expertise along with years of experience allows us to respond quickly with solutions tailored to your needs of cast film production. At HB Machinery, every unit of cast film line can be engineered and retrofitted to entirely fulfill your specific needs.
Raw Material Dosing SystemIntermittent agitator and continuous gravimetric feeder are provided in a selection of various weights, ensuring consistent blending of ingredients, accurate dosing and repeatability. A single extruder can be equipped with multiple dosing units.
Extruder The extruders for cast film are typically designed to meet the specific characteristics of the extruded materials and processing requirements. According to the size of extruder and processed materials, the screws can be provided with armoured flights for a better performance of wear resistance.
Feed BlockFeed block enables the cast film variable in number of layers. In the process of CPP production, 3-layer feed block is commonly configured with 3 extruders. For films with 5-layer structure, a tailored solution will be provided to fit actual request.
Flat DieFlat die provides an excellent uniformity of the thickness distribution, resulting in optimization of the thickness variations on each single layer with a minimized tolerance of film thickness. This performance shortens extrusion time and ensures a higher efficiency.
Casting StationThe first chill roll is characterized by an electro-chemically matted surface that can reduce air entrapment and provide high cooling effect, which makes the film to be easily released. The second and the third chill rolls can be added for adapting to actual needs.
Winding SystemThe winding system is designed with functions of trimming, embossing and slitting. We provide various winding systems with optimization focused on the aspect of automation to meet customers’ needs. All of these winders feature robust steel structure which can reduce vibrations produced by dynamic forces during the production process at high speed.
CPP Film LineThis cast film line is primarily used to produce multilayer (three-layer or five-layer) co-extruded CPP and CEVA films, as well as PA/EVOH high barrier films.
CPE Film LineThe cast film line utilizes LLDPE/ MLLDPE/LDPE/HDPE as base material to produce multilayer co-extruded CPE film with high transparency.
PVC transparent Packing Film LinePVC transparent Packing Film Line uses PVC compounded material that is fully mixed with recipe components to produce various high quality clear films and embossed films, a wide broad of specifications is available per customers’ requirements.
Since its establishment in 1998, HB Machinery has been recognized as a leading manufacturer of cast film lines. Our cast film and sheet extrusion lines are widely applied in a wide variety of industries including food packaging, pharmaceutical goods, building supplies, material handling.
