Product Description

Brief features of our Preform mold
Cold-half Mold features
Neck rings designed in two parts to ensure the same axial degree of preforms in molding;
Optimized water-cooling channels to enhance preform cooling in mold and to guarantee fast cycle time;
Mold stacks are made of S136 stainless mould steel; the steel will be heat treated before finish tooling;
Plates and other parts of the frame are made of 420  stainless mold steel.
Hot-half Mold features
Hot-runner channels have the top engineering in balance design;
Main parts of hot-half mold such as heaters, valve-stems are imported from Europe;
Drops are controlled individually and heating zone temperatures are adjustable, AA value from thermal degradation is minimized.
Mold test:
The finished mold will be tested in our factory before delivery.
Preform Acceptance
Preforms molded from us PET mold are in optical clarity international standards;
Preform wall thickness variation within 0.12mm can be achieved for preform with standard neck;
Preform will be accepted in accordance with preform drawing.
Warranty Clause
18-month warranty starting on the date of mold dispatch our factory;
Claim or damage from customer's own operation mistakes reason shall not be applicable.
Remark:
Recommended chilling water temperature for mold cooling is 7-10ºC.
Preform Acceptance criteria

Attribute	Specification
Thread tolerances	Thread tolerances are as per the International Society of Beverage Technologists "ISBT" standards. If the thread finish type is not within the ISBT standards, tolerances will be based on the approved preform drawing. All ISBT standards can be viewed at
2) Thread dimensions inspected (Coca China only check  E, T, D, ID, "A" points dimension and calculation for these five points shall be>1.33)	Standard dimensions inspected are as per the drawing shown
3) Individual preform weight     variation from nominal (used minus tolerance)	Nominal weight	Tolerance
	Less than 20g	± 0.2 g
	20g to 35g	± 0.3 g
	Greater than 35g to 50g	± 0.3 g
	Greater than 50g	± 1 %
4) Maximum allowable weight variation between preforms in one shot. On an Index system, one shot is defined as a "single" face of the mold.	Nominal Weight	Tolerance
	Less than 35g	0.2g
	35g to 60g	(≤0.3g)
	Greater than 60g	(0.5%×preform weight)
5) Wall thickness variation   Max. Min.	Wall thickness variation = maximum wall thickness minus minimum wall thickness Measured on the body within 3mm of the cavity/gate insert parting line
6) Ovality	Maximum ovality of the preform not to exceed 0.2mm. in the body of the preform Ovality = maximum diameter minus minimum diameter
7) Perpendicularity              (prior to re-heat)	Max 0.75mm Ave: 0.5mm
8) Overall length ( excluding gate protrusion)	Preform length		Tolerance
	Up to and including 120mm		± 0.5mm
	Over 120 mm		± 0.5% of perform length
9) Crystallinity	Crystallinity in gate area: to be within 8mm diameter centered on gate tip (for preform base diameter less than 35mm) Crystallinity through the gate area: to have a depth less than 50% of the bottom wall thickness Crystallinity in body: not acceptable
10) Sink marks	Not acceptable
11) Parting line deformation (Valid for Index molds only)	Parting line deformation "PLD" on preform body :  Many factors effect PLD including , preform design, parting line location, processing conditions Wall thickness less than 4.00mm.: Max. 0.20mm Wall thickness 4.0mm and greater: Max. 5% of wall thickness (Wall thickness measured and neck ring/cavity parting line)
12) Scratches	Can not see by visual inspection
13) Mismatch between parting lines (excluding any mismatch designed into the preform)	0.05mm(maximum)
14) Flash	0.05mm (maximum)
15 ) Bubbles or unmelts	Not acceptable
16) Short shots	Not acceptable
17) Surface contamination	Inner and outer surface to be free of foreign material, e.g. dirt, grease, oil, … Not Acceptable on inner and outer surface of preform unless determined to be a result of the pet resin used
18) Embedded contamination	Not acceptable
19) Gate length	Max: 1mm
20) Hole in injection point	Less than 1.0mm deep
21) Cold slugs	Not acceptable
22) Haze	Not acceptable
23) Moisture rings	Not acceptable
24) Degraded material	Not acceptable
25) Gate lines	Not acceptable
26) Weld lines top of vent	Not acceptable
27)  Polarized light	Stress within a preform can be detected by the use of polarized light. Preform design, resin and processing conditions all affect the stresses within a preform. As the stresses shown by polarized light are subjective, this tool will only be used for reference.
