Molding FAQs
Practical answers about high-temperature materials, precision fits, and custom robotic components.
Which plastics should be considered for parts near robotic motors?
PEEK, PPS, PEI, and PPA are among the materials that may be evaluated. Selection depends on continuous and peak temperatures, exposure time, mechanical load, insulation needs, and the specific grade. Share the expected temperature at the component and its operating conditions for review.
How do you choose between PEEK and PPS for robotic components?
We compare mechanical requirements, temperature exposure, chemical environment, wear conditions, and cost. Reinforcement and additives can significantly change performance, so the comparison should use specific grades and application data rather than resin names alone.
Will high-temperature plastics maintain precise assembly fits?
Assembly fit depends on molding shrinkage, thermal expansion, moisture absorption, fiber orientation, and part geometry. Critical interfaces should be defined on the drawing and assessed under the intended operating conditions. Tooling adjustments or secondary machining may be considered for selected features.
Can molded plastic replace metal in a robotic assembly?
Selected housings, covers, guides, and brackets may be suitable candidates. The review considers stiffness, creep, fatigue, heat dissipation, fastening, and dimensional requirements. Conversion often requires changes to wall thickness, ribs, and connection features.
Can you mold gears, bushings, and other wear components?
These components can be reviewed for injection molding. Material and geometry depend on load, speed, mating material, lubrication, temperature, and required service life. Wear performance should be validated under representative operating conditions.
Can metal inserts and soft gripping surfaces be integrated?
Insert molding can integrate threaded inserts or terminals, while overmolding can add compatible gripping or cushioning materials. We review insert retention, material compatibility, bonding, and temperature exposure before recommending the manufacturing approach.
What information should I provide for a quotation?
Send your 3D CAD files, available 2D drawings, material specification, and expected quantities. Include critical tolerances, operating temperatures, loads, mating parts, and inspection or testing requirements. If the material is undecided, share the application conditions for review.
