Read article -Temper, cool, and peel decide whether a silicone cavity fits the bar. Polycarbonate still wins when you need a hard gloss and a high cavity count.
Read article -There is no cycle count that fits every tray. A tear at the same corner means redesign. Yellowing alone does not.
Read article -Vacuum time follows viscosity, the cup size, and pot life. A timer does not replace a look at the cup.
Read article -Ask which article was tested, for which food, at which temperature, and for which market. A drum PDF is not this tray.
Read article -Shore A does not keep a chocolate logo sharp. The stroke width, the depth, and the peel do.
Read article -A flat master in a box is a one-piece mold. A figurine with undercuts is not a kitchen pour. This page is the home method, not a production tray.
Read article -If the part will not peel, the mold needs a split, a slit, or a plug. A softer Shore A will not pull a hook through a closed cavity.
Read article -There is no single HS code for every silicone mold. Your broker classifies the shipment. We keep the invoice description consistent.
