Cooling Circuit Design Deciding the Cycle a Quote Assumes
Cooling circuit design dictates actual injection cycle time; quotes assuming unrealistically fast cooling cause part warpage or forced piece-price increases.
Piece Price Re-Indexing
Meaning
Pricing adjustment mechanisms link the unit cost of a manufactured component to the fluctuating price of raw material feedstocks. piece price re-indexing allows molders and buyers to reset commercial terms based on public resin indices or energy benchmarks at fixed intervals, and it applies as long as the underlying contract remains active.
Cost Calculation
The formula uses a baseline resin price and adds a fixed conversion fee for labor and overhead. When the market price of the resin moves outside a narrow band, the total price of the part is recalculated. This method ensures that the molder does not lose money on material costs and the buyer pays a fair market rate.
Market Volatility
Sudden changes in oil or gas prices can cause resin costs to spike by twenty percent in a single month. Without a re-indexing agreement, these fluctuations create financial risk that can stop production. The mechanism provides a predictable way to handle these shifts without constant negotiation.
Contractual Certainty
Both parties agree on which independent index will be used to track the market. This transparency prevents disputes about the actual cost of the raw material. The agreement defines exactly when the price will change, such as the first day of every quarter, to allow for better budget planning.
