A sliding interface beneath the fixture
This drawing-defined acetal component connects a fixture to a matching guide channel. The concept combines a wide upper flange with a narrower continuous underside tongue. Two recessed fixing holes illustrate the attachment pattern. The tongue locates within the customer's channel while the upper face provides an interface for the moving tooling. Rail, drive, end stops and installation hardware are outside the molded-part supply scope.
The intended design direction is an automation fixture slide, where a nest or tooling element travels between defined positions. It differs from a conveyor side guide that contacts passing packages. The slide itself does not establish the final station position: the surrounding mechanism, stop arrangement and control system determine how movement ends and how the fixture is held.
Start with a section through the guide
A complete cross-section is more useful than an overall length alone. Show the channel opening, internal width, depth, corner radii and the surfaces intended to carry contact. Identify whether the tongue sides guide movement, whether the flange underside rests on the channel shoulders, and where vertical clearance is needed. The illustrated T-shaped outline is a starting concept, not a standard rail size.
Running clearance must be assigned between the actual mating surfaces. The flange overhang shown in the illustration is not a clearance dimension. Please provide the tolerance range of the mating channel as well as the nominal dimensions. Also identify the entry direction: a slide that fits through an open channel end may be impossible to install in a guide closed at both ends.

Keep fasteners clear of the motion envelope
The recessed holes require a defined screw-head diameter, recess depth and remaining plastic section. Confirm which side the tooling attaches from and where the nut or threaded mating feature sits. Hardware must not project into the travel path. The drawings should also explain whether the screws fix the slide to a moving nest or serve another assembly function; tightening through the stationary guide could prevent the intended motion.
Please specify the working stroke, number of slides supporting one fixture and the point where force enters the assembly. An off-center attachment can introduce a moment that a simple width check misses. Provide the stop design separately so that the plastic slide is not unintentionally treated as an impact buffer. No positioning accuracy, permissible load or operating life is assigned by this listing.
From assembly requirements to a molded component
Before tooling, review the flange-to-tongue transition, draft, wall sections and permissible parting-line locations. Mark sliding contact zones where a gate witness or flash would interfere with movement. If selected features need secondary finishing, define them explicitly rather than assuming every molded surface will have the same finish or tolerance.
For quotation, send the CAD model, guide drawing, tooling attachment pattern, expected quantities and installation environment. Include the mating material, contamination conditions, intended lubrication approach and cleaning exposure. POM grade selection and fit should be reviewed for those conditions. These visuals are concept illustrations and do not document a tested assembly, certification or previous production run.
Sample acceptance can then address full-stroke movement, installed fastener clearance, fixture alignment and fit at the specified inspection conditions. Application validation and replacement criteria should be agreed for the actual machine.
