Custom PP Float Shells for Tank Level Sensing
A float that rubs against its guide tube can give an inconsistent switching position. This custom polypropylene housing is developed around the clearance between the central bore and the sensor stem, together with the displacement needed to carry the finished float assembly. SWKS supplies drawing-based injection molded shell components for level sensing projects in chemical storage and dosing equipment.
Define the float around the liquid and stem
The annular form leaves a guide passage through the middle while the surrounding cavity provides buoyancy after suitable joining. Outer diameter, overall height, bore diameter and shell mass must be considered together. A larger cavity alone does not establish the switching level: liquid density, any magnetic insert, assembly weight and travel stops also influence the operating position.
Natural PP is an available material direction. The final resin grade should be selected against the actual liquid, concentration, temperature and exposure period. Chemical compatibility, pressure limits and service life require project-specific validation; they are not implied by the housing material name.
Molded halves and the joining interface
The shell can be divided into two molded sections with a defined peripheral joining land. Draft, wall transitions and gate placement are reviewed to support filling and limit distortion near the guide bore. Joining method and energy director geometry are agreed during development. A leak-tight finished float requires an approved joining process and inspection plan; unjoined shells are not functional sealed floats.
Drawing review checklist
- Guide stem diameter, bore clearance and permitted lateral movement
- Target float mass, liquid density and required immersion position
- Space for an optional magnet or other customer-specified insert
- Joining land dimensions and allowable seam projection
- Fluid composition, operating temperature and cleaning conditions
- Critical tolerances, appearance zones and annual demand
Sample approval and inspection
Initial samples can be evaluated for bore size, concentricity, shell weight and fit on the intended guide. For an assembled design, the customer and supplier should define leak testing, buoyancy checks and free movement throughout the sensing travel. Acceptance criteria are established before production rather than inferred from a catalogue illustration.
Typical development uses
Drawing-based float shells may be considered for chemical day tanks, additive reservoirs, dosing skids and other guided level sensor assemblies. This item is a customized mechanical housing, supplied to the agreed scope; sensor electronics and installation hardware are specified separately.
The images illustrate a representative custom configuration. Production geometry, dimensions and performance follow the approved drawing and sample.
Request a quotation
Provide an STP, STEP or IGS model, a dimensioned drawing, the liquid specification and estimated order quantities. Identify whether you need molded halves only or a reviewed joining and assembly scope.
