Trial Your Own Plastic in a Servo-Hydraulic Molding Machine Demo
A buyer's guide to planning a demonstration of a servo-hydraulic injection molding machine using the buyer's own plastic material, with questions for the RFQ and acceptance test.
Ask the supplier to run your own plastic in the demonstration, not a house sample. Because the machine is servo-hydraulic and intended for forming plastics, the trial should show how the clamp and injection units respond to your material's behavior, not just cycle an easy resin.
For the RFQ, state your polymer grade and the part or workpiece you want molded, and ask which screw diameter the supplier proposes; catalog values across the series run from 24 to 220 mm, and clamping force spans 600–33,000 kN, so confirm the proposed configuration rather than assuming a series figure fits your tool. Ask whether the demonstration uses your mold or a representative one, how drying and regrind are handled, and what process data are recorded.
In the demonstration, compare shot consistency across consecutive cycles, watch clamp movement and pressure build, and ask for the servo-hydraulic response to be explained at the settings used. For acceptance, agree on measurable criteria tied to your material and part.
Before requesting a quote, confirm with the supplier which material lot will be run, who supplies the mold, what data the trial report includes, and whether the demonstrated settings are documented for the acceptance test.
