Custom PET Preform Mould for Personal Care & Household Liquid Bottles

1. Finished Bottle & Preform Product Features

Product Specifications: Multiple volume options (100ml, 200ml, 500ml, 1000ml) straight cylindrical bottle body, standard multi-start threaded neck for pump caps, flip caps and screw caps

• Material Options:
  1. Opaque milky white PET (light shielding, suitable for light-sensitive skincare formulas)
  2. Fully transparent clear PET (visible liquid display for shower gel, hand sanitizer)
• Surface Performance: High-gloss smooth surface, no weld lines, bubbles or crystallization haze after blow molding
• Core Function: PET preforms are injection-molded blanks, then blow molded into finished liquid packaging bottles for personal care, beauty and household chemical industries

2. Core Mould Technical Advantages

• Cavity & core inserts: S136H / STAVAX anti-rust stainless steel, mirror polished Ra ≤0.02μm
• Nitriding surface treatment, compliant with FDA, RoHS and cosmetic packaging safety standards
• Effectively eliminate PET crystallization, white fog and surface defects for high-gloss bottle appearance

• Full surrounding spiral water channels for each cavity and long core pin
• Uniform temperature control for tall cylindrical preform bodies, avoid warpage, uneven wall thickness and shrinkage marks
• Shorten injection cycle time by 25–35%, boost hourly production output for mass packaging orders

• Customizable cavity quantity: 8/16/24/32 cavities for different output demands
• Symmetrical hot runner manifold ensures equal melt flow distance to all cavities, preform weight deviation ≤±0.02g
• Hot runner design eliminates cold runner waste, reduces raw PET material cost for long-term mass production

• Integrated long sleeve ejector fully wraps slender preform bodies, synchronous balanced ejection
• Prevent neck thread scratches, preform bending and sticking during demoulding, suitable for tall cosmetic bottle preforms

• Thickened 718H pre-hardened steel mould base, resist high PET injection pressure
• Service life: 800,000 ~ 1,200,000 continuous shots for 24-hour factory operation
• All standard components adopt HASCO international standard for easy global maintenance

3. Application Scope

Finished Bottle Usage

• Beauty & personal care: Shampoo, conditioner, body wash, facial lotion, toner, cosmetic spray bottles
• Daily household chemicals: Hand sanitizer, disinfectant, laundry detergent, cleaning agent bottles
• Industrial liquid packaging: Mild reagent, household spray liquid containers
