The Slide Slitting knife is used for side-cutting both at high web speeds or in applications were low friction is an absolute must. The knives are suitable for side cut-ting of “all kinds” of lay-flat films in blown film lines – i. E. “sticky” thin film or Heavy-duty layflat HDPE- and LLDPE within the range of 15 to 500 microns.
Manual Screen changers are designed to minimize extruder downtime compared to changing screen packs by disassembling the head. When it is time to change screens, by using the handle, screen changer manually slides the clean screen pack into the flow stream and the used clean screen pack into the cleaning position.
A discontinuous screen changer may be come in different design. It generally consists of a sliding plate that houses two breaker plate/screen pack assemblies. One assembly is in the flow stream to provide melt filtering. The other is located outside of the flow stream and is accessible for removal, cleaning, and replacing for later use. When it is time to change screens, the screen changer is activated hydraulically and slides the clean assembly into the flow stream and the used assembly into the cleaning position.
The melt pump is widely used in extrusion machines, resin and rubber products, such as film, pipes, sheet and so on, and their primary function is to keep the stable extrusion rate and stabilize pressure of polymer. Flextrusion offers a wide range of melt pumps for various type of polymers
Carbon fiber rollers, including both dead and live shaft idlers, are converting rollers that are primarily used when both high strength and low weight are needed.
They are basically aluminium or rubber roller having unique groove pattern on roll surface. The cushioning and resonance of grooved spreader rollers are achieved due to groove pattern, which makes these rollers capable of handling delicate films without any damage during wrinkle removing process.
Our water temperature controllers use water as heating medium and processes under direct cooling method for heating up to 120℃ and our TCU oil circulation temperature controller use heat transfer oil as heating medium and processes under indirect cooling method for heating up, the highest temperature can reach 200℃.
Dehumidifying Dryers are designed to eliminate moisture in the plastic material before processing. Air is forced through a desiccant bed to make it extremely dry. This air is then heated to a specified temperature and fed into a Drying Hopper containing the material to be dried. This hot dry air draws the moisture out of the material; the saturated air is then fed out of the Drying Hopper and back through the desiccant bed again to remove the moisture before the cycle begins again. Our dehumidifying dryer is powerful and its heated air flow system and unique air circuit are designed for evenly temperature control and the best quality.
Engineered for a wide variety of cooling or heating applica-tions. Unique inner shell spiral design controls cross product temperature differentials and overall heat transfer character-istics. Proprietary computational analysis for guaranteed me-chanical and thermal performance. Surface finishes and tol-erances to meet your processing requirements. Manufactured to stringent industry standards and safety practices.
Bubble cooling deserves much attention. In many blown film operations, it is the limiting factor to maximizing throughput. Flextrusion offers quality custom build cooling coils. Our cooling coil body is fabricated from heavy gauge stainless steel, includes inlet air filter and is fully insulated. Three-way temperature operated water flow control valve to control constant temperature of cooling air to air ring.
Flextrusion conveying systems are designed to ensure the correct functioning with granules with different bulk Density. We also provide solutions for handling at high temperature keeping granule dehumidification constant up to the inlet of the injection moulding machine or into the extruder screw. In these cases, important construction and engineering details are considered as well as the closed loop mode.
Our hoppers constructed from full stainless steel, and depend on type of product can be fitted with reed switch sensor or with Photo sensor. All model equipped with the mechanical flapper and auto-filter cleaning as standard.
Magnet drawers are primarily used in plastics processing to prevent metal chips damage extruders. These magnet drawers provide economical continuous protection against costly machine downtime for all types of plastic resin processing machinery. Mounted directly on the feed throat of your plastic processing equipment.
