Our Products
Sai offers standard application finished screws through flight tipping as well as fully encapsulated screws. This combined with corporate research and development, has enabled Sai to offer barrel material, screw finishes and screw geometries for nearly every extrusion machine and plastics processing application.
Screw designs within the Sai have evolved over several decades from simple single flight Geometries to sophisticated barrier/mixing designs. State-of-the-art advances in screw design have improved the melting and solids conveying capabilities of the single screw extruder, leading to higher productivity. The most significant advances in melting are being realised due to our patented barrier screw geometriesSai can supply almost any size of extrusion screw for almost any application, and also offer a comprehensive rebuilding service too.
Just remember the most important element in any extrusion system is the feedscrew and is responsible for the critical functions of feeding, solid conveying, melting, mixing and pumping.
Feedscrew Technology Our ability to design and manufacture some of the industry's most advanced and efficient feedscrews is one reason we have been an extrusion leader for more than 10 years. With our R&D facilities and team of experienced polymer process engineers, we offer customers world class screw design and technical capabilities.

BarrelsOur primary manufacturing facility is in the single screw production, service, and support. We build one piece barrels ranging in bore size from 1 to 20 inches (25 to 500mm) in diameter and up to 185 inches (4, 700mm) long. Two piece barrels are available in lengths ranging from 185 to 295 inches (4, 700 to 7, 500mm).

Quick Turn
Barrel AlignmentThe purchase of a new barrel or screw can often be a considerable expenditure for an organisation, not perhaps in the initial purchase price of the replacement part but in the time, planning and lost production in making the change.
It is essential that companies therefore protect that investment and ensure that their new components are installed in the appropriate manner. The alignment of the barrel, feed housing and gearbox drive shaft are critical in the installation to avoid premature wearing of the components and subsequent loss in production rates in the future.
Sai understands these issues and offers a laser alignment service to ensure that these components are in their optimum condition before production restarts.
Our visiting engineer will measure the initial deflection and then assist your production staff in making the simple adjustments until the positioning of the components are as near to nominal as possible, thus protecting your investment for the future.
Inspection & Measuring Screws and barrels used in plastics/rubber processing naturally wear over time and companies often don't realize the consequences that this wear process can have on the quality and quantity of production from their machinery.
Sai understands implicitly these issues and offers an Inspection and Measuring Service to help customers determine how to maintain their machinery in peak condition.
Our visiting engineer will inspect both barrel and screw conditions and submit to the client a written report on the condition of the components and the recommended remedial action required, if any.
Again, Sai will work with you to protect your production equipment from the consequences of worn and/or deteriorating components.
The Sai single screw extruder is a product of heavy research & development. This confirms the dominance of Sai in extrusion field.
The Gear Box is designed for transmitting the high torques & for coping up with the maximum thrust load. It has space saving construction. High efficiency is achieved with helical gears of high quality forged steel, hardened & ground.
The Thrust housing is designed for bearing the maximum force and not allowing the thrust pressure to damage the reduction gears as Sai provides high quality Thrust Roller Bearing.The screw is combined with a special grooved barrel having a properly equilibrated geometry.The melting process is determined by the barrier zone. Separation between the solid and liquid phase is achieved, maintaining the solid bed up to the complete melting.The role of metering zone is to homogenize the molten material and give high output without pulsation.
The space saving Mobile Extruders usually operators in conjunction with the fixed horizontal extruder. Thus in combination provides extra flexibility to insulate automotive wires, optical fibre buffering etc. and also employed as an auxiliary extruder for skin insulation, striping &colouring.

The Sai Powder on the product and the size of the product. The brushes are smoothening the through passing product and are taking away the surplus of the powder material which is continuously fed back into the powder storage chamber by means of a step less speed adjustable rotating screw (AC-Drive converter). The brush set rotation speed is driven by a chain transmission from the screw Applicator is design to apply powder e.g. Chalk, Talc, Calciumstearat or Graphit on cables, profieles or hoses. The application of powder on the through passing product is done by means of a rotating bridge preventor spring as well as by an adjustable set of 3 counter rotating brushes. The brush set is adjusted according to the needed amount of powder. There is an inspection hole above the brush set in order to supervise the brushes during operation so that the rotation speed of the screw/brush set can be adjusted accordingly. Also available is a provision on the outlet side after the brushes to connect a vacuum suction device to remove even more powder from the product if necessary. Refill of powder is done during continuos operation by pouring powder into a funnel directly over the powder chamber. The powder chamber is electrically heated, preventing the powder from clogging and absorbing humidity. The complete unit is movable on wheels, adjustable to line height and can be used for continuous application of powder to cables, hoses, profiles a.s.o. All parts in direct contact with powder are made out of stainless steel. The operator panel is easy reachable above the machine and can be swivelled around to adjust to the line direction.The Powder Applicator acc. to draw. no. 3-300041-02 corresponds to the new European regulations and is delivered with the CE-label and a conformity certificate.

This traversing type unit allows to keep the cable straight at all times during the haul off process.Bobbin load/unload, locking/unlocking and traversing operations are fully motorized.
When using dual pay off/take up, the front stand can be moved aside from the machine's center line, allowing to used the rear stand thus getting a continuous run.
The machine is provided with MMI+PLC control system for pre-setting traversing pitch and for drum speed control.
When using large cable, the pay off can be equipped with a speed detecting dancer for speed synchronization.
The pay off system is a necessity for continuous production. Two housings made of mild steel iron are so placed that the out let of the wire comes in the centre. The inner end of the wire and the starting endof the full reel are led out of a horizontal slot of the housing and welded together, thus ensuring a continuousrun. Each housing is equipped with a reel lifting carriage containing the mandrel for the reels, the flyer disk and the AC motor. The wire is paid off via the flange of the non-rotating reel which is lifted on the spindle driven by a reversible three phase AC motor. The motor is fed via a plug-in cable from the control board.
Travel drive for reel carriages movable by an AC motor. At the Pay off housing a wire change detection is mounted. The device gives a signal if a reel change is necessary to have continuous production.
The Capstans offered by us are available in different sizes of pulley and diameter that vary as per the small & medium size of cables and line speed. Capstan role in extrusion line is to pull the wire from Extruder and offering it to take-up in a synchrony form of speed.
