2L HDPE Jerry Can
2L HDPE View Stripe Jerrican Blow Molder 44kN 50kg/h 4 Head IML Slot Neck Trim Servo
The 2L HDPE View Stripe Jerrican Blow Molder 44kN 50kg/h 4 Head IML Slot Neck Trim Servo is a production-ready extrusion blow molding machine engineered for manufacturers of 2-liter HDPE jerricans with transparent view stripes. Combining a 44kN clamping force, 50kg/h throughput, four extrusion heads, an in-mold labeling slot, automatic neck trim, and servo-driven control in an integrated unibody frame, it delivers stable output with minimal commissioning overhead.
From a process engineering standpoint, clamping force determines how consistently the mold holds the parison during blow inflation. At 44kN, this machine is sized for the wall-thickness uniformity that chemical and daily-chemical jerricans require. The servo drive provides position-feedback precision across every stage of the cycle — clamp open, parison extrusion, clamp close, blow, and re-open — replacing conventional hydraulic speed control with repeatable closed-loop timing.

Key Engineering Features
4-Head Layout for Balanced Output
The 4-head layout maintains 50kg/h throughput while distributing parison heat evenly across all cavities. Single- or dual-head machines targeting the same output often push individual head temperatures higher, raising the risk of HDPE degradation. The 4-head configuration avoids this by spreading the extrusion load, supporting wall-thickness consistency across continuous production runs — not just during sample approval.
IML Slot for In-Mold Label Integration
The mold carrier includes an IML (In-Mold Labeling) slot that positions the label before blow inflation. This eliminates the adhesive step used in post-blow labeling and reduces peel risk for chemical jerricans under storage or transport conditions. A label integrated during the blow cycle becomes structurally bonded to the container wall and resists delamination from solvent, moisture, or heat exposure that post-applied labels may not.
Servo-Driven Cycle Precision
Servo control minimizes cycle time variation between shots. Pushing throughput to its absolute limit typically comes at the cost of wall-thickness consistency and scrap rate — the servo system helps operators find and hold the optimal operating point rather than chasing a theoretical maximum. In sustained 8-hour production, this supports more consistent batch-to-batch timing compared to conventional non-servo speed control.
Automatic Slot Neck Trim
The neck trim station removes flash at the container mouth within the main clamp cycle, eliminating a separate offline deflashing step. For chemical jerrican production, a clean neck finish directly affects cap seal performance and leak prevention — critical for regulatory compliance with liquid chemical fills. The synchronization ensures neck trim does not create a bottleneck at 50kg/h output.
Unibody Frame for Fast Commissioning
The integrated unibody structure arrives from the factory with extrusion head alignment, leveling, and hydraulic connections pre-configured. This design, refined over nearly 20 years of market use, contributes to reduced on-site commissioning time — a practical consideration for packaging OEMs with tight launch timelines.
Application Scenarios
Chemical and Agrochemical Packaging
The 2L HDPE View Stripe Jerrican Blow Molder 44kN 50kg/h 4 Head IML Slot Neck Trim Servo is well-suited to chemical and agrochemical fills where leakage prevention, solvent resistance, and fill-level visibility are required. The seamless blow-molded body eliminates weld lines that could become leak points under pressure or vibration. The view stripe allows end-users to check fill levels without opening the container — a practical requirement in industrial chemical dispensing and regulated handling environments.
Daily Chemical and Household Products
Detergent, cleaning concentrate, and disinfectant producers use 2L jerricans for institutional supply chains. The IML slot enables brand-consistent label integration on the same line without a secondary labeling station — useful when producing for multiple brand customers with mold and label changeovers. The servo drive maintains repeatable cycle parameters across changeovers, supporting consistent quality between product runs.
Lubricants and Automotive Fluids
Gear oil, hydraulic fluid, and brake fluid producers use 2L jerricans for workshop and aftermarket packaging. The automatic neck trim produces consistent neck geometry for torque-sensitive cap application on filling lines. HDPE compatibility with these chemistries, combined with 4-head dimensional consistency, supports stable batch quality in automotive fluid packaging.

Frequently Asked Questions
What is the lead time?
Customized configurations typically require approximately 60 days from deposit confirmation. Stock units ship faster. Provide container dimensions, output requirements, and IML label specifications for an accurate lead time estimate.
Which plastic materials are compatible?
HDPE, PE, and PP. HDPE is standard for jerricans due to its chemical resistance and structural rigidity at 2L dimensions. PE and PP changeovers require process parameter adjustment to match each material's melt behavior.
Does Tongda provide installation and training?
Yes — experienced technicians are available for on-site commissioning, installation guidance, and operator training. Remote 24-hour technical support is also standard via video conference or online channels.
Are spare parts supplied?
A standard spare parts package ships with the machine. Contact Tongda for the configuration-specific packing list. Spare parts inventory is maintained throughout the machine's service life.
