Hi everyone! I’m working on reheater tubes for an ultra-supercritical boiler operating around 700 °C and 28 MPa. I’m evaluating Inconel 617, 740H, Alloy 263, and Super 304H for their high-temp creep strength, oxidation resistance, and... read more

I’m designing a compact linear stage for a lab automation setup, used to move a microplate (about 300 grams) precisely along a 150 mm travel. The system needs to achieve repeatability under ±0.05 mm... read more

Hello, I'm designing a plastic coupling sleeve to mount an aluminum shaft (20 mm OD) from the inside. The sleeve needs to grip the shaft firmly enough to transmit rotational torque from a small... read more

Hi! My project is a small-scale marine sensor housing; it needs to stay functional when briefly submerged (around 0.5 m depth) or exposed to heavy splashes on a boat deck. I’m using a machined... read more

Hi! Currently working on a small batch of U-groove guide rollers for a linear transfer system, and I'm using a soft polyurethane tread (around 85A Shore) bonded to aluminum hubs. The supplier estimates each... read more

Hi, I've got a batch of aluminum brackets that need to be drilled and milled on all sides with high repeatability. Has anyone designed a modular fixture system for parts like this to reduce... read more

Hi all! I’m building a compact gimbal for a sensor head that needs to rotate around two perpendicular axes (pan and tilt). I’m trying to stay away from standard U-joints — they take up... read more

I’m planning to use vacuum casting to produce about 50 housing units with integrated snap-fit features for an electronics prototype. The parts need to survive multiple assembly/disassembly cycles during testing. I’ve seen mixed opinions... read more

Hi, I created a 3D design for a small microfluidic part using SLA (Clear Resin) with internal channels ~0.4 mm wide and wall thickness around 0.5 mm. The function relies on optical inspection through... read more

Hi there, I need to add a part number and recycling symbol on the surface of molded parts in PP GF20 for outdoor use. I initially planned to use engraved text for aesthetic reasons,... read more
