Versatile Mold Applications for PET Packaging

Applications

Every Industry’s Bottle Starts with Our Preforms and Molds

Applications

Baijinyi specializes in delivering high-precision blowing molds and preform injection molds, empowering the production of plastic containers across diverse sectors, including beverages, food, daily chemicals, pharmaceuticals, and beyond. Our molds are engineered for compatibility with leading equipment brands, seamlessly integrating with preform injection machines (such as HUSKY, NETSTAL, SIPA, KM, and KAT) and blow molding machines (including Sidel, Krones, KHS, SACMI, Newamstar, and Tech-Long), ensuring versatile, high-quality output for your production needs.

Beverages

The largest market for PET packaging, with PET bottles accounting for over 70% of global beverage packaging.

Mineral Water and Carbonated Drinks Single-layer PET bottles dominate, demanding molds that deliver high clarity, robust pressure resistance (≥1.6 MPa), and rapid molding cycles (≤8 seconds).

Juices and Functional Beverages Molds must support acidic formulations (pH ≤3.5) and hot-fill processes (85–90°C), featuring enhanced cooling systems to minimize thermal deformation risks.

Alcoholic Beverages For beer and pre-mixed drinks, molds are optimized with oxygen-barrier designs (using multi-layer co-extrusion technology) to extend shelf life.

Food Industry

Edible Oil Bottles Designed for high-temperature filling (≥60°C) and leak-proof performance, our molds feature reinforced rib designs and precise wall thickness control (±0.1 mm).

Condiment Bottles For corrosive liquids like soy sauce and vinegar, molds are coated with hard chrome or DLC for enhanced durability and extended lifespan.

Instant Food Packaging For microwaveable meal containers, our molds leverage in-mold labeling (IML) technology to create heat-resistant (up to 120°C) and deformation-proof structures.

Why Us

Expertise in Beverage Mold Design

With deep experience crafting molds for all types of beverages, we tackle production challenges from the design stage, driving cost savings and efficiency:

Aseptic Beverages Our designs proactively address issues like poor bottle formation, cold-storage collapse, insufficient vertical pressure, bottle tipping on lines, or airflow inefficiencies, ensuring flawless output.

Carbonated Drinks We incorporate advanced venting designs for superior base formation, reducing line disruptions from tipping and cutting high-pressure air usage.

Hot-Fill Beverages Optimized mold shrinkage ratios enable precise capacity adjustments, lower energy demands, and lightweight designs that reduce costs without compromising performance.

Lightweight Solutions From the outset, we engineer designs to meet clients’ cost-saving lightweight goals.

Unmatched Manufacturing Strength

Our production prowess sets us apart, churning out approximately 200 blowing molds per month, around 2,400 sets annually, alongside an average of two preform injection molds monthly, delivering reliability at scale.
