Product Description
Long Neck PET Bottle Preform & Specialized Injection Mould
 

1. Finished Preform Product Features

  • Structure: Long straight cylindrical body, rounded bottom, standard threaded neck for screw cap assembly
  • Material: Virgin bottle-grade PET, milky white opaque or fully transparent customizable
  • Function: Intermediate blank for blow molding plastic bottles for drinking water, cosmetic lotion, disinfectant, detergent liquid packaging
  • Surface finish: High gloss smooth surface without flow lines, bubbles or crystallization haze
  • Standard neck thread design ensures leak-proof matching with standard plastic caps after blow molding


2. Core Mould Technical Advantages


✅ Food-Grade Mirror Polished Stainless Steel Cavity
  • Cavity & core inserts: S136H / STAVAX stainless steel, mirror polished to Ra ≤0.02μm
  • Anti-rust nitriding treatment, fully compliant with FDA, NSF food contact safety standards
  • Eliminates PET crystallization, white fog and optical defects for consistent glossy preform appearance

✅ Independent Spiral Conformal Cooling System
  • Full surrounding spiral water cooling channels for each long cavity and core pin
  • Fast heat exchange shortens injection cycle time by 25–35%, controls uniform wall thickness on long cylindrical body
  • Separated cooling inlet/outlet circuit for every single cavity to avoid temperature difference between cavities

✅ Balanced Hot Runner Multi-Cavity Layout
  • Customizable cavity quantity: 8/16/24/32 cavities available for high hourly output
  • Symmetrical hot runner manifold design, equal melt flow distance to each cavity, preform weight tolerance ≤±0.02g
  • No cold runner waste, reduce raw material cost for mass packaging production

✅ Full Sleeve Balanced Ejection Structure
  • Long integrated sleeve ejector matched with long core pins, synchronous uniform ejection
  • Effectively prevent neck thread scratch, body deformation and sticking during demoulding of long slender preforms

✅ High-Rigidity Heavy-Duty Mould Base
  • Mould base: 718H pre-hardened steel, thickened frame to resist high PET injection pressure
  • Service life: 800,000–1,200,000 continuous shots for 24-hour mass production
  • All standard components follow HASCO / LKM international specifications


3. Material & Application Scope

A. Compatible Raw Material: Virgin bottle-grade PET, anti-UV modified PET, opaque white masterbatch PET


B. Finished Product Application

  • Tall beverage plastic bottles, mineral water & functional drink packaging
  • Cosmetic spray bottles, lotion and skincare liquid containers
  • Household chemical bottles: disinfectant, detergent, cleaning agent bottles
  • Industrial small liquid reagent plastic packaging bottles
