What micro-part data should a buyer prepare before requesting a GEERPOWER all-electric injection molding machine quotation?
Prepare part weight, runner weight, resin grade, critical dimensions, mold layout, cavity count, handling method and inspection method. Machine selection, shot repeatability, tolerance, output and acceptance remain NEEDS_EVIDENCE until the GEERPOWER configuration and trial basis are defined.
Decision checklist
- Provide measured part and runner weights, not only product photos.
- State whether the project uses a cold runner, hot runner or special runner strategy.
- Define critical dimensions and measurement method before asking for tolerance claims.
- Include part removal and collection because handling can decide real yield for micro parts.
Micro parts are not only smaller precision parts
Very small molded parts can make shot size, runner ratio, melt residence time, mold venting, part handling, static loss and metrology more important than a headline clamp-force comparison.
The RFQ should show whether the project is driven by part weight, runner design, material sensitivity, inspection requirements or downstream handling loss.
A useful micro-part quote needs a measurement method as much as a machine route. Otherwise the precision claim has no acceptance basis.
Separate shot, resin, mold and metrology
ARBURG micro-injection molding material emphasizes melt preparation, short residence time and first-in-first-out behavior for micro components. Electric-machine references support the broader all-electric route, but they do not validate a future GEERPOWER project by themselves.
Buyers should use these sources to structure the project file and keep exact performance claims evidence-gated.
- Part and runner weight with cavity count.
- Resin grade, drying need and degradation sensitivity.
- Mold size, cavity balance, venting and gate concept.
- Handling route for tiny parts after ejection.
- Critical dimensions, gauge method and sample size.
Technical limitations
Public micro-molding and all-electric references support the checklist, but they do not prove GEERPOWER micro-shot repeatability, cleanroom suitability, medical acceptance or tolerance performance.
Selected model, injection unit, screw diameter, residence-time review, handling method, metrology, sample result, price and delivery remain NEEDS_EVIDENCE until confirmed for the exact project.
Common buyer questions
Is an all-electric machine automatically required for micro parts?
No. All-electric architecture can be relevant, but the choice still depends on part weight, resin, mold, handling, inspection and production target.
Can GEERPOWER confirm micro-part tolerances before seeing the drawing?
No. Tolerance, repeatability and sample acceptance remain NEEDS_EVIDENCE until the drawing, mold, resin, machine route and inspection method are reviewed.
Why is runner weight important?
For very small parts, runner weight can dominate the shot. Without that data, the injection-unit and material-residence discussion may be wrong.
