Research
How settings shape a part
Pressure, temperature and time decide whether a part comes out whole. A small change can spoil it.
Industry source
Resin suppliers' processing guides for injection molding
Setting a press by trials
Short trials that change one setting at a time find the band where a mold makes good parts.
Industry source
Plastics trade press: articles on setting an injection press by measured trials
Scrap removed in published cases
Published cases report scrap down by one to three percent of the resin, on molds with sensors.
Supplier's claim
Case studies published by suppliers of pressure sensors for molds and of technician training
Sensor and course prices
Sensors inside a mold are a purchase for each press. A course for a technician costs far less.

Suppliers of pressure sensors for molds: prices given on request
Training providers' listed course fees
Cost of a scrapped part
A scrapped part has used press time and labor too. We count less than published figures do.
