1800BPH Semi Automatic 4 Cavity Pet Bottle Blowing Machine

Introduction of Semi Automatic PET Bottle Blow Molding Machine

The 4 Cavity Semi Automatic PET Bottle Blowing Machine is a highly efficient and cost-effective solution designed for small to medium beverage producers who need stable bottle quality without the investment of a fully automatic system. This machine combines manual preform loading with semi-automatic bottle blowing, giving factories greater flexibility, lower operating costs, and fast return on investment.

Engineered for water, juice, edible oil, carbonated drinks, detergent, and other packaging applications, this semi-automatic blowing machine for PET bottles can produce bottles up to 3 liters with consistent wall thickness and excellent transparency. Its robust heating system uses infrared lamps to ensure uniform preform heating, while the high-pressure blowing system ensures precise forming inside high-strength, durable molds.

The NC-4 model adopts a compact layout, allowing easy installation in small workshops while still delivering an output of up to 1800 bottles per hour. Operators can quickly change molds to adapt different bottle shapes, making it ideal for startups, customized bottle production, trial runs, or factories that need flexible bottle sizes without complicated automation.

Designed with user-friendly controls, this manual PET bottle blowing machine requires minimal training. The machine structure is built from high-quality steel, offering stable performance, low maintenance, and long service life. It is also compatible with semi automatic PET water bottle blowing applications where hygienic, lightweight, and cost-controlled bottle production is required.

Whether you're looking for a reliable plastic bottle blower for daily production or an economical solution for multiple bottle sizes, the 4 cavity semi automatic PET bottle blowing machine offers an ideal balance of efficiency, affordability, and bottle shaping precision. It helps manufacturers improve productivity, reduce labor costs, and ensure consistent bottle quality in every production batch.
