Что такое Литье полимеров от экспертов СибСталь: ## 1. Job Overview
This video demonstrates the industrial manufacturing process of stretch blow molding hollow plastic bottles. Heated preforms are placed into high-precision metal molds and inflated with high-pressure air to form durable, uniform plastic containers.
## 2. Materials & Equipment Used
— Preheated plastic preforms (orange)
— Automated industrial stretch blow molding machine
— Custom metal bottle mold cavities
— High-pressure compressed air inflation system
— Mechanical transfer arms and conveyor assembly
## 3. Step-by-Step Procedure
1. Preheating: Plastic preforms are loaded into a specialized heating unit to soften the material for shaping.
2. Mold Placement: The softened preforms are manually transferred and positioned securely into the metal mold cavities.
3. Mold Clamping & Air Injection: The mold closes tightly, and high-pressure air expands the preforms to conform perfectly to the mold dimensions.
4. Cooling & Ejection: The newly expanded plastic bottles cool rapidly within the mold before being opened and released.
5. Final Inspection: The finished orange bottles are retrieved and checked for structural integrity and surface smooth consistency.
## 4. Importance of the Process
Stretch blow molding allows for high-volume, cost-effective production of uniform lightweight containers with exceptional structural strength and clarity, essential for various consumer packaging industries.
