What Are the Steps Involved in the Two-Stage Blow Molding Process?
这 two-stage blow molding process separates preform production from bottle forming into two physically independent operations, which is why it is also called the two-step blow molding machine method. In the first stage, PET or PETG resin pellets are injection-molded into test-tube-shaped preforms and cooled to ambient temperature. These preforms can be warehoused, transported, or fed immediately into the second stage. In the second stage — handled by this EP-HGA.FS-1CG150 — the preforms are reheated through an infrared oven, stretch-rods lengthen them axially, and high-pressure air expands them radially inside a precision steel mold to form the finished bottle.
This architecture delivers several practical benefits over a single-stage approach. Resin conditioning in stage one can be tuned independently of blowing speed in stage two, enabling tighter control over haze, stress-whitening, and top-load strength. It also makes this stretch blow molding machine ideal for high-volume cosmetic and personal-care packaging where dimensional repeatability is non-negotiable. Compared to single-stage machines, two-stage systems typically offer higher output per cavity, better preform flexibility, and simpler mold changeovers — factors that matter when your SKU range includes multiple bottle profiles.

Mold Engineering — Preform & Blowing
Preform Injection Mold
The gate bushing is built as a two-part assembly, guaranteeing coaxial alignment throughout the preform formation cycle — a key factor in avoiding gate stress that can lead to bottle haze or crystallinity issues during blowing.
The internal cooling channel layout has been optimized to maximize thermal extraction during each cycle, shortening cycle time while keeping preform temperatures stable across the entire batch.
All cavity-forming elements are machined from imported grade 2316 die steel, which provides inherent rust resistance and has been subject to controlled heat treatment for hardness and longevity.
Core plates, cavity plates, and structural frames are fabricated from 420-grade stainless steel to resist the corrosive environment of a high-humidity production floor.
Standardized interchangeable fittings simplify maintenance, and the intelligent design means a single mold toolset can accommodate more than one preform specification — reducing tooling inventory for multi-SKU operations.
Blowing Mold
The cavity block is forged from high-grade tooling steel, selected for its combination of hardness, thermal conductivity, and dimensional stability under repeated pressure cycling at 35 kg/cm² blowing pressure.
Every bottle profile is developed using professional 3D modeling software, enabling the engineering team to verify parting-line placement, draft angles, and undercut geometry before a single cut is made in metal.
A wide portfolio of bottle templates is available for selection — oval, round, asymmetric, and multi-panel formats — giving cosmetics brand owners flexibility without requiring fully bespoke tooling on every launch.
The water-cooling circuit is routed to minimize temperature differential across the mold face, producing consistent wall thickness and gloss whether the line is running at startup or at full steady-state speed.
Every metal component is finish-machined on multi-axis CNC equipment, ensuring the cavity surface finish and parting-line precision required for high-clarity cosmetic PET and PETG packaging.
How to Choose the Right Blow Molding Machine for Your Application
选择正确的 bottle blow molding machine requires matching machine capacity to your specific bottle geometry, resin type, and production volume targets. The EP-HGA.FS-1CG150 is the right choice when all of the following conditions apply: your target bottle is in the 50–2,500 ml range, the resin is PET or PETG, you require high cosmetic-grade clarity, and your preforms are sourced externally or from a separate upstream injection line.
If your container exceeds 2,500 ml or requires more than one cavity in the blow station, consider the FS-1CG196 or FS-2CG220 models from the same series. If you process PE or PP resins and your packaging is a squeezable tube or technical container, an extrusion blow molding machine from a different product family would be the better technical match.
For buyers in Colombia, Latin America, and other markets where voltage and compressed-air infrastructure differ from Chinese factory standards, our technical team provides pre-delivery equipment configuration, site acceptance testing documentation, and commissioning support — ensuring the auto blowing machine arrives production-ready. This matters especially for pet blowing machine manufacturers supplying turnkey lines, because utility compatibility is typically the first on-site variable to address.

常见问题解答
Which industries in Colombia most commonly use a fully automatic PET blow molding machine for cosmetics bottles?
In Colombia, the personal-care, household-chemical, and pharmaceutical sectors are the primary adopters of fully automatic PET blow molding machines. Major producers of shampoo, body lotion, liquid detergent, and over-the-counter liquid medicines rely on high-clarity PET and PETG containers to differentiate their products at retail. The FS-1CG150, with its wide neck-diameter range and 2,500 ml capacity ceiling, covers virtually the entire bottle portfolio that these Colombian manufacturers require — from 50 ml pump-top serums to 1.5-litre family-size shampoo bottles — without requiring multiple machine models.
What are the key differences between single-stage and two-stage blow molding for PET cosmetic bottles, and which approach produces better clarity?
Single-stage machines inject the preform and blow the bottle in the same unit, which minimizes resin handling but limits the ability to fine-tune heating independently of injection conditions. Two-stage machines — like the EP-HGA.FS-1CG150 — separate these steps, allowing operators to run preform injection at its ideal resin temperature and then condition preforms in a dedicated oven at the exact temperature profile needed for biaxial orientation. For cosmetics packaging, where optical clarity and wall uniformity directly affect perceived brand quality, the two-stage process typically delivers better results, because the infrared heating oven can target specific zones of the preform with more precision than the heat retained from a single-stage injection cycle.
How does an automatic bottle blow molding machine handle both PET and PETG resins on the same production line without changing major components?
The FS-1CG150 manages PET-to-PETG transitions primarily through the heating oven's zone temperature settings, which are saved as named recipes on the HMI. PETG has a broader processing window and slightly lower orientation stretch ratios than standard PET, so the infrared lamp intensity and oven speed are adjusted accordingly. No mechanical components need to be swapped — the stretch rod stroke, blowing pressure, and cooling water settings remain within range for both resins. Most operators complete a resin changeover in under 30 minutes, including the time needed to purge residual preforms from the loader and run a short trial before releasing production bottles.
Where can pharmaceutical packaging manufacturers in Latin America source a reliable two-step stretch blow molding machine with after-sales support?
Pharmaceutical manufacturers in Latin America — including Colombia, Brazil, and Mexico — typically look for a supplier who can provide CE-certified equipment with multi-language documentation, validated IQ/OQ commissioning support, and a responsive spare-parts channel. Our team provides remote commissioning assistance, English-Spanish bilingual manuals, and a regional spare-parts inventory accessible via air freight. The EP-HGA.FS-1CG150 is CE-marked and has been supplied to pharmaceutical bottle producers across multiple Latin American markets. For buyers who need local validation documentation for regulatory filings, our quality team can provide material certificates for mold steels and full dimensional inspection reports for cavity tooling.
How do I determine whether the EP-HGA.FS-1CG150 blow molding machine is the right capacity for my cosmetics production volume requirements?
Start with your annual bottle volume target and divide by your available production hours to get a required bottles-per-hour figure. The FS-1CG150 delivers a theoretical output of 700 bph; accounting for standard efficiency factors (changeovers, maintenance, and startup time), a realistic net output is typically 550–620 bph for experienced operators running PET cosmetic bottles. If your net requirement falls below this range, the FS-1CG150 is a right-sized match. If it significantly exceeds this capacity, consider the FS-1CG220 or a multi-machine layout. Our technical team can run a capacity analysis based on your bottle weight, neck diameter, and shift pattern at no charge before you commit to a purchase decision.
