Winding frame around a valve actuator tube
This PBT frame supports the winding package of a customer-designed solenoid valve actuator. Its round tunnel surrounds the specified tube or pole arrangement, and its end flanges establish the winding envelope. The valve actuator section should identify the stationary tube, moving plunger and external magnetic return components. The supplied molded frame is the bare insulating structure; the winding, metallic tube and connector contacts are separately specified items.
Tunnel fit and magnetic assembly clearance
The bore must accept the actual actuator tube with the clearance and assembly direction defined by the valve designer. A long tunnel can amplify an alignment error, so circularity, straightness and the flange references may all be relevant. The frame should not force the tube out of position or obstruct a pole shoulder. The magnetic air gap and plunger movement remain properties of the complete actuator, not dimensions inferred from the plastic former alone.
Winding space and end-flange boundaries
Usable winding length is the distance available after flange geometry, insulation layers and process allowances are included. Supply the conductor arrangement and the permitted outer winding envelope. The flanges should support the intended winding sequence without relying on wire tension to reshape them. A rectangular exterior flange with a cylindrical barrel can require orientation features so the connector pedestal remains correctly clocked relative to the valve body.
Lead-out pedestal and contact locations
A connector pedestal can locate start and finish connections where the approved design uses an integral terminal area. Hole pitch, recess depth and lead channels need to match the selected contacts and joining process. Empty molded holes shown in the image do not include pins by default. Describe whether contacts are inserted before winding, fitted later or integrated through another approved process, because this sequence changes access and tooling requirements.
PBT compound and actuator heating
The resin proposal follows the actuator temperature envelope, electrical insulation needs and manufacturing exposures. Continuous energization, short pulses and the surrounding valve temperature can produce different duty conditions. Provide the approved thermal requirements rather than deriving a service temperature from the polymer name. Flame or electrical classifications refer to the selected grade and supporting documents, with the completed valve coil validated under the customer defined operating cycle.
Encapsulation and sealing boundaries
Some solenoid assemblies encapsulate the winding or place it inside a separate protective casing. Identify the encapsulant or overmolding material, cure conditions and the interfaces that must remain free of material. A lead channel, tube tunnel or locating flange can become blocked if the finishing process is not included in the design review. The plastic frame is not assumed to be the valve pressure boundary; fluid sealing is established by the approved actuator and valve construction.
Winding equipment access and fixture datums
Show the winding mandrel and the surface used to hold the empty frame during coil build. Fixture compression should not change the tunnel or end-flange spacing beyond the approved condition. A winding nozzle also needs clearance around the pedestal and lead notches. Where a sleeved wire crosses a flange, identify its route and minimum available space so the finished connection can be assembled without trapping the sleeve against the casing.
Trial build of the valve coil package
First-off frames can be evaluated through contact installation, winding, joining and the chosen finishing process. Record the tunnel fit before and after those stages and check that the completed package fits the intended magnetic assembly. The actuator designer specifies electrical, thermal and endurance trials at the relevant assembly level. Dimensional inspection of the empty frame can include tunnel form, winding length, pedestal location and flange distortion.
Solenoid-specific quotation requirements
Send the actuator section, tube diameter, winding envelope, connector arrangement and required PBT grade. Include duty cycle, surrounding temperature and any encapsulation or finishing process that affects the frame. State whether the offer covers the bare plastic item or additional assembly operations. A controlled drawing and expected quantities allow SWKS to define tooling, samples and inspection around that particular valve coil configuration.
