aluminum-alloy injection-blow mold

aluminum-alloy injection-blow mold for precision bottles

Aluminum-alloy injection-blow molds are used for forming small, high-precision bottles and jars in cosmetics, pharmaceuticals, and food, combining injection-positioning and blow-expansion advantages to achieve high-precision necks, uniform wall thickness, and good surface quality.

Description

Aluminum-Alloy Injection-Blow Mold Overview

If you need optimization for output capacity, resin type (e.g., PP, PE, PETG), surface finish, or anti-counterfeiting requirements, please provide the specific bottle design and process parameters so the mold design can be customized accordingly.

Key Features

  1. Material and heat dissipation: Aluminum-alloy molds conduct heat quickly and respond rapidly to temperature control, helping shorten molding cycles and improve dimensional stability.
  2. Precision and surface quality: The injection-blow process shapes the bottle mouth and threads during injection to ensure cap/pump fit accuracy, while the blow stage ensures uniform wall thickness and smoothness.
  3. Production efficiency: The mold is relatively lightweight for easy installation and maintenance; fast heat transfer can increase cycle rates, suitable for mass production.
  4. Service life and maintenance: Aluminum alloy is corrosion-resistant; hard coatings on cavities or steel inserts can reinforce wear-prone areas, making repair and replacement convenient.
  5. Customization capability: Supports multi-cavity layouts, various bottle shapes (round, square, irregular), calibers, thread specifications, and surface textures, with options for anti-counterfeiting engraving or logos.
  6. Application scenarios: Cosmetic serum bottles, lotion bottles, small-capacity pharmaceutical bottles, small food seasoning bottles, and portable disinfection/cleaning spray bottles that require precise necks and uniform wall thickness.
