blow molding machine

Blow Molding Machine Sourcing is an independent sourcing partner for US plant buyers who need factory quotes on extrusion and injection blow molding machines. Share the part, mold envelope, resin, quantity and destination so manufacturers can confirm platen fit, takeout clearance and quotation boundaries. PET bottle stretch-blowing is outside this site’s equipment family.

Duty and operating envelope

Material entering the machine
Name the resin family and condition (for example HDPE or PP pellets, moisture, regrind percentage) because feedstock viscosity and parison strength change head tooling, accumulator volume and leak-test limits. Do not substitute a generic plastics label for the grade that will run in production.
Required output
State bottles or kilograms per hour together with the mold cavity count, flash ratio and the inspection plan. Nominal catalog throughput is not a plant guarantee; suppliers should quote the test conditions that support any cycle-time figure.
Duty cycle
Describe shifts, planned changeovers and whether the line must restart after a stop with the same wall-thickness window. Continuous extrusion and accumulator concepts behave differently after idle time, so the operating schedule belongs in the RFQ, not as an afterthought.

Resolve procurement unknowns

Clamping force in kN does not prove the mold fits the platen, opening stroke and takeout path. Capture the known mold envelope first, then ask each manufacturer to mark remaining gaps before comparable quotes exist.

Known input
Part drawing or sample, mold length/width/height, neck finish, expected cavities, and whether takeout is robotic or gravity. Include the intended connected load window if the plant already knows voltage, phase and frequency.
Supplier confirmation
Platen dimensions in mm, opening stroke, tie-bar or C-frame envelope, and written confirmation that the mold and bottle can leave the work envelope without colliding with the blow pins or calibration stations.

Where a blow molding machine sits in the plant

Known input
Bottle family (jerrycan, handleware, cosmetic bottle), layer count, and whether upstream drying or downstream leak testers already exist. Those facts decide if the RFQ is a single machine or an interface-heavy cell.
Supplier confirmation
Why continuous extrusion or an accumulator head is proposed for that part, plus compressed air demand, cooling water, footprint and PLC interface assumptions that the buyer’s utilities team must still verify on site.

Which quotation route fits the current brief?

Does the mold already exist, or is the container still a concept?

Defined specification

If platen size, stroke and resin are known, send those values with quantity and destination so manufacturers can return comparable machine and tooling boundaries. Read the mold envelope note before treating force-only quotes as complete.

Send requirements

Selection still open

If the part is not frozen, ask for a shortlist of machine families and the trial method instead of a single model number. Review sourcing steps so each bidder states the same included items.

What stays outside this procurement scope?

Factory ownership, authorized-brand status and guaranteed output are not claimed here. Certificates belong to the named supplier and product. PET stretch-blow lines, civil works and utility upgrades remain separate unless a bidder prices them explicitly.
