The CDS downstream medical tubing extrusion line includes a vacuum sizing tank, cutter unit, and takeaway conveyor.

Extrusion machinery provider Custom Downstream Systems Inc. (CDS; Lachine, QC, Canada) has launched a new line of downstream extrusion equipment for medical tubing applications. The line includes a high-precision vacuum sizing tank, a combination servo belt haul-off and servo fly-knife cutter unit, and a takeaway conveyor.Designed to provide the precise shaping requirements of medical tubing applications, the vacuum sizing tank, model CMPVS 8-8, features an efficient water cooling system and high heat-transfer rate. To maximize operator control and reduce downtime, the tank is constructed with exterior product-support rollers, retractable water reservoirs, and water-level adjustment functions. These features enable the operator to make adjustments to the machine without halting production. Horizontal and lateral movement of the tank is controlled by manual knobs, but the unit also allows three-axis movement via a PLC.The model CMCBSSK 2-125 combination servo belt haul-off and servo fly-knife cutter unit features cut-to-length and x-y cutter adjustment designed to provide high accuracy and pulling capabilities. It has a maximum cut length of 254 m, minimum cutting capacity of 0.254 cm, and offers a cut-to-length accuracy of ±0.03 cm. To ensure overall quality and consistency, the unit has an integrated lubrication system and the machine also includes an easy blade-replacement channel for operator safety.To efficiently collect extruded products, the model CMTC 4-10 takeaway conveyor is designed with an adjustable frame that has front-mounted controls, which allow for independent line speed adjustments within a 39-45-in. range. Such adjustment capability can reduce product-collection costs while increasing overall productivity, according to the manufacturer. Monitoring of the unit's speed is made easy with a control that indicates the conveyor's movement in feet per second. The machine also has a pneumatic ejector that discharges to a product collection tray and exterior ribbing designed to reduce the risk of residue accumulation.
