// Injection molders · Quoting

Quotes for molded parts, drafted around the numbers your estimator sets.

For custom and contract molders. One job, tested on RFQs you already quoted. AI reads the package, fills your quote sheet from your own rates and resin prices, and keeps piece price and tooling apart. On new parts, cycle time, cavity count and the mold price stay blank for your estimator; on repeat parts they come from your records.

// The one job

An RFQ lands. Your quote sheet comes back mostly filled.

A buyer sends a drawing, a model, a resin callout and an annual volume, for one part or a family of them. Your estimator works out the shot, picks a press, judges the cycle and cavities, gets a mold price, adds secondary work and packaging, and writes the quote. Much of that is gathering facts already in the package or your rate sheets.

For the test, AI works through copies of RFQs you already answered and drafts your quote sheet line by line, every rate traced to your own sheets. Repeat parts and re-quotes get cycle time and cavity count from your records, with the source shown. On new parts those fields stay empty, beside a list of what the package left out.

// What the estimator watches

Where a molded-part quote goes wrong

Material is priced on the shot, not the part. Resin cost starts from the shot weight, every cavity plus the runner, divided back across the cavities. A hot runner leaves little or no runner to pay for; a cold runner leaves one to regrind or scrap, and some customers forbid or limit regrind. Machine cost is the press's hourly rate times the cycle time, divided by the cavities. The draft shows each input and its source: your resin price list, your press rates, or a blank for your estimator.

A resin callout carries more than a name. A brand and grade followed by "or equivalent" still needs the customer's written approval for any substitute. Color may come precolored or as a concentrate at a let-down ratio, and the two price differently. A UL 94 rating holds only at the thickness on that grade's UL Yellow Card, and a colorant can affect it, so a V-0 callout on thinner walls becomes a question for the buyer. Medical parts add a grade listed as tested to USP Class VI or ISO 10993, a cleanroom class under ISO 14644-1, and validation work your shop may quote separately.

The tool is its own quote. Tooling sits apart from piece price, priced by your toolmaker or tool room. The RFQ may name an SPI mold class, from Class 101 for a million cycles or more to Class 105 for prototype tools of about 500 cycles or fewer, and an SPI finish from A-1 diamond buff to D-3 dry blast, or a texture number. Each moves the tool price, so the draft carries every callout into the toolmaker request and never prices the mold. Terms count too: one automotive supplier's published tooling terms bar a tooling invoice before full PPAP approval, and the draft notes terms like that on the tooling line.

Volume, families and transfers change the math. Cavity count usually follows the estimated annual usage, so a volume range needs a quote at each point your estimator picks. A family mold splits one cycle's cost across different parts, so a buyer who drops one part reprices the rest. A transfer tool, a customer's mold coming from another molder, may arrive with that molder's process sheet or with nothing; the draft uses only what is written and lists the mold evaluation as open. Ultrasonic welding, pad printing, heat-set inserts, assembly and packaging, from bulk boxes to returnable dunnage, come from your own rates.

Your reviewer. The owner names the person who knows your quoting best, usually the lead estimator, who checks each line against the quote that went out: shot weight and runner, resin price, press class, secondary and packaging lines, tooling callouts and every question raised for the buyer. Include a family mold or a transfer tool if you quote them.

// What you send

What your quoting desk sends

Copies only
Commercial programs only
01

20 to 30 past RFQs

The buyer's package for each, drawings and models included, with the quote sheet your estimator built and the quote that went out. A mix of new parts and re-quotes makes the fairest test.

02

Your rate sheets

Press rates by tonnage class, secondary operation and packaging rates, and your scrap and margin rules, the way your estimator uses them. A spreadsheet or a page of notes will do.

03

Resin prices for those dates

The resin prices your estimator used when each RFQ was quoted, from distributor quotes or your price list, so drafts price material the way you did then.

04

The toolmaker quotes

The tool quotes behind those RFQs, so the tooling line in each draft can be checked. The draft carries a tool price; it never makes one.

05

An NDA, then copies

Signed before any drawing moves, since customer models usually carry the customer's own confidentiality terms. No login to your ERP or quoting tool. If drawings can't leave the plant, we build look-alike packages with you.

// Before it starts

Written down before the first RFQ moves

// After a yes

About 30 days on incoming RFQs

After a yes, new RFQs get a draft quote sheet and a question list as they arrive, for about 30 days.

Your estimator fills the judgment fields, checks every line and decides what goes out. No quote reaches a buyer unless a person sends it, and the same scoring table runs through the live month.

    After that

// One hard limit

It never sets a cycle time, a cavity count or a tool price.

On new parts those numbers come from your estimator and your toolmaker, and the draft leaves them blank. On repeat parts it carries forward what your records show and marks the source. Margin, the final price and what goes to the buyer are your calls, and defense and aerospace RFQs never come in.

Molded-part quoting gets its own price: a range before the test, a fixed price before you sign.

The range depends on how many RFQs arrive in a month and how many are re-quotes of parts you already run.

// Questions

Quoting questions

Can AI work out the cycle time from the wall thickness in the model?
Not in this proof of concept. Cycle time depends on wall thickness, resin, cooling and your presses, and that judgment stays with your estimator. The draft can list cycle times your records hold for parts in the same resin and press class, marked as reference only.
Our buyers give a volume range instead of one annual number. How is that quoted?
Your reviewer sets the rule before the test, such as quoting at the low, middle and high volume. The draft follows it and flags any volume where your past quotes used a different cavity count.
Does it get mold prices from our toolmakers?
No. It drafts the tooling request with the RFQ's callouts, such as mold class, finish and texture, and puts the toolmaker's price on the tooling line once you have it. During the test it uses the toolmaker quotes you send.
We mold for medical customers. Do those RFQs fit?
Yes, if your reviewer includes them. The draft reads the resin grade, cleanroom and validation callouts and prices each from your rates. Where a requirement points to a document the package doesn't include, it becomes a question for the buyer.
Do we have to change how we quote?
No. The draft follows your quote sheet's layout, whether you quote in your ERP or in a workbook, and the test runs on copies. How drafts reach your system is settled for the live run.
