Product Overview
PET preform production is driven by repeatability: neck finish accuracy, preform weight consistency, and thermal balance. Our moulds are designed for stable production windows—reducing scrap, downtime, and cost per preform over the full lifecycle.
Preform Specification Coverage
Share your neck finish standard and target preform weight. We align mould layout, gating, and cooling to your resin/IV, output requirements, and blowing line compatibility.
Neck Finish Control
Critical dimensions and sealing surfaces are treated as “must-hold” zones to ensure cap fit and leak prevention.
Weight & Wall Consistency
Cavity balance and process window validation help keep weight variation and defects under control for stable blowing.
Output Planning
Cavitation and cycle-time targets are designed together—so your total output matches annual demand with predictable uptime.
Typische Anwendungen
Engineering & Mould Design Highlights
Thermal Balance for Stable Cycle
Balanced cooling reduces hot spots and shortens cycle time while maintaining consistent preform geometry.
Valve Gate & Flow Control
Hot runner + valve gate solutions are selected to support consistent filling, reduce gate defects, and improve repeatability.
Wear Strategy & Long Mould Life
Wear-critical areas are designed for durability and serviceability to reduce downtime and protect long-term output.
Low Tooling Price vs Lower Total Cost of Ownership (TCO)
In PET preform production, the real cost is driven by stable cycle time, controlled scrap, and reliable uptime. Compare quotes with a production-first view—not only the invoice price.
Real tooling details matter for uptime and scrap control—key drivers of TCO in high-cavitation preform production.
Quote A: Lowest Price
- Cooling design simplified; thermal imbalance risk
- Limited validation; narrow process window
- Higher risk of neck variation, short shots, stringing
- Maintenance shows up earlier in production
Quote B: Optimized for TCO
- Balanced cooling for stable cycle time
- Hot runner/valve gate matched to your resin & output
- Defined scrap assumption + measurement at trial
- Serviceable wear areas to reduce downtime

PET-Vorformling Form: FAQ
Strategic Insights: PET Preform Mold (Mould) Tooling
Built for buyers comparing suppliers on TCO: cycle stability, neck finish consistency, maintenance, and mold life.
1) What defines a high-performance PET preform mold (mould)?
A high-performance PET preform mold is built for repeatability at speed: a balanced valve gate hot runner for clean gate quality and a cooling layout designed for stable cycle time. The goal is consistent preform weight and neck finish for high-speed blowing and downstream cap fit.
2) How do you control concentricity in PET preform tooling?
Concentricity drives uniform wall thickness. We use cavity/core location control (anti-shift / self-locking features) and verify alignment during assembly and trial to reduce eccentricity risk and improve blow consistency.
3) What hot runner system do your PET preform molds use?
We commonly apply valve gate hot runner systems for PET preforms to avoid sprue waste and improve gate finish. Temperature control and balance are set up to keep melt distribution stable across cavities.
4) Can you manufacture high-cavitation PET preform molds?
Yes. We build high-cavitation PET preform molds (typical ranges include 16–144 cavities, depending on design). The focus is balance (runner + cooling + venting) so output stays stable at scale.
5) What steels/materials do you use for long mold life?
For PET preform cavities/cores, we typically use corrosion-resistant, polishable tool steels (e.g., S136 class) with proper heat treatment and surface finishing to support long service life and optical clarity requirements.
6) How do you achieve faster cycle time in PET preform molds?
Cycle time is mainly driven by heat removal. We optimize cooling channels near gate/neck regions and critical thickness zones, and select insert materials/structures based on the preform weight, wall thickness, and required clarity.
7) Why are interchangeable inserts important in PET preform tooling?
Fully interchangeable cavity components simplify maintenance: you can replace a single cavity set instead of pulling the full mold. This reduces downtime and helps keep production predictable for high-volume plants.
