Attention
Neck finish is not a small detail
A buyer may search for PCO1810, PCO1881, 30/25, 29/25 or 38mm because the cap and filling line already require a standard. The mold quote should start from that standard.

Neck finish and cap fit
Neck finish affects cap compatibility, preform design, neck rings, mold parts and quotation accuracy. Confirm the neck standard before comparing PET preform mold prices.

Decision points
Attention
A buyer may search for PCO1810, PCO1881, 30/25, 29/25 or 38mm because the cap and filling line already require a standard. The mold quote should start from that standard.
Interest
Neck finish affects neck ring design, closure compatibility, preform weight, inspection gauges and sometimes application choice. A drawing or cap sample reduces the risk of quoting the wrong mold.
Desire
The feature is a specified neck finish; the advantage is correct mold part design; the buyer benefit is avoiding quotes that look similar but are not technically comparable.
Action
Send the neck drawing, cap sample photos, bottle application, preform weight, cavity target and machine model. If you only know the cap type, send photos and measurements.
Supply process
Step 1
Drawing, cavity, neck finish, weight and machine data.
Step 2
Prepare project data for mold quotation and capability matching.
Step 3
Compare scope, steel, hot runner, spare parts and trial terms.
Step 4
Production progress, inspection coordination and export communication.

FAQ
A preliminary review is possible, but the safest quote needs a neck drawing, cap sample photos, standard name or measurements. Cap size alone may not define the full neck finish.
Yes. Neck ring design, parts precision, preform weight and inspection requirements can change the mold scope and price.
Please send the preform drawing if available, cavity number, preform weight, neck finish, bottle application, injection machine model, target output and destination country. If you do not have all details, send what you have and we will help clarify the missing points.
