Daily Chemicals & Cosmetic Bottle Blow Molding Machine Types

Understanding Our Model Names

A quick guide to decoding our One Step Blow Molding Machine specifications to find the perfect fit for your production line.

Example Model Breakdown
EP-HGA.ES Серия машин
-
2 Cavities
C Identifier
114.3 Pitch (mm)
-
Daily Chemical Plastic Bottle Blow Molder Application / Type
Core Specification Logic (e.g., 2C100, 3C76, 4C76)

The most critical part of our model number directly indicates the mold configuration, which determines production capacity and product size limits.

[Number] e.g., 2, 3, 4
+
C Stands for "Cavity"
+
[Number] e.g., 76, 100, 114.3

1. Number of Cavities (e.g., 2)

Indicates how many bottles the machine can produce in a single cycle. Higher numbers mean higher output rates.

2. Pitch Distance (e.g., 114.3)

The center-to-center distance between adjacent mold cavities in millimeters (mm). This dictates the maximum diameter of the bottle you can produce.

Why This Series

Engineering Advantages

Every machine in the series shares a common engineering foundation refined over two decades of production development.

Servo Motor Efficiency

International-brand servo motors deliver torque proportional to actual mechanical load. Normal operating power stays well below installed capacity — reducing per-bottle energy cost across multi-shift schedules without sacrificing cycle consistency.

Two-Stage Process Control

Separating preform conditioning from the blowing cycle lets each phase run at its own optimum. Preforms reach the blowing section at a precisely uniform temperature, giving every cavity identical material input — the direct source of consistent wall thickness across cavities.

Special-Shaped Bottle Capability

The series is specifically engineered for bottles with high difficulty and high requirements — asymmetric shoulders, faceted sidewalls, narrow long-neck profiles. Precise stretching rod control and adjustable blowing pressure fill demanding cavity geometries without wall failure.

Scalable Cavity Architecture

2-cavity, 3-cavity, and 4-cavity configurations share a consistent machine platform. Producers can match cavity count to annual volume targets and scale up as demand grows — without retraining operators or changing tooling program management.

PET and PETG Compatibility

Both resins are fully supported across the series. PET delivers clarity and recyclability for standard daily chemical lines; PETG adds impact resistance and deeper color saturation for premium personal care and prestige cosmetic packaging programs.

Mold Design

onestepblowmachine-preform injection mold
  • Two-part die lip design maintains strict coaxial alignment during preform formation
  • Optimized cooling channels extract heat uniformly, shortening cycle time without dimensional variance
  • Cavity-forming components machined from imported 2316 die steel after heat treatment
  • Core and cavity plates manufactured from 420 stainless steel throughout
  • Standardized fitting system supports interchangeability across the mold program
  • Single toolset can accommodate multiple preform specifications
onestepblowmachine Blowing Mold
  • High-grade steel selected for surface hardness and thermal conductivity
  • Every profile validated in 3D CAD before machining — parting geometry, vents, fill dynamics
  • Wide library of pre-engineered daily chemical and cosmetic bottle profiles available
  • Cooling passages engineered for thermal uniformity across the full cavity surface
  • All metalwork finished on CNC machining centers to production-grade tolerances
