Technical Data
High-precision Two-Component Resin Injection Machine from source factory Zhongsheng. Features 60L dual tanks, 1.2 cc/rev Cr12MoV gear pumps, and automated static mixing.
Applicable:
Epoxy resin Polyurethane Phenolic resin Two-component pultrusion resins
The Two-Component Resin Injection Machine (internationally designated as an automated closed-mold metering system or resin injection machine) is engineered by Henan Zhongsheng for the automated metering, precise proportioning, uniform mixing, and continuous quantitative feeding of two-component thermosetting polymers—such as epoxy resin, polyurethane, and phenolic resin systems. Synchronized with active gantry traction velocity and daily glue consumption, this machinery ensures the fluid mixture remains fresh, optimizing resin-fiber wet-out and matrix cross-linking inside the pultrusion die cavity.
The material conditioning and supply matrix features dual isolated 60L storage tanks engineered with active motor components to handle continuous raw material pretreatment prior to injection:

| Cleaning Unit | • Flushing: Automatic air-and-solvent alternating purging cycle phase. • Requirement: Must be performed immediately after every single composite production session. |
To secure long-term plant manufacturing ROI and operational compliance, Henan Zhongsheng backs each machinery deployment with complete engineering lifecycle services:
NOTE: Standard machinery configuration excludes tank thermostatic systems and hose heating jackets. These parameters can be fully customized and retrofitted based on actual plant production requirements and polymer viscosities (≤20000Mpa.s).
This automated dual-component resin injection machinery provides a turnkey closed-mold feeding solution for high-volume pultrusion manufacturing lines, perfect for processing: Polyurethane Cooling Tower structures, High-Voltage Epoxy Cable Trays, Phenolic Mass-Transit profiles, and heavy-duty structural sections requiring flawless fiberglass wet-out quality.
| Operational Matrix Vector | Zhongsheng Two-Component Injection Machine | Traditional Open-Resin Bath Tank |
|---|---|---|
| Resin Pot Life & Material Waste | Maximized (Continuous inline mixing keeps compound fresh) | Poor (Large volume exposed, cures early, high material waste) |
| Fiber Wet-out & Micro-void Limits | Flawless (Closed-die constant injection pressure) | Standard mechanical scraping (Prone to internal air bubbles) |
| Volumetric Dosing Precision | Elite (≤±1% via Cr12MoV servo gear pumps) | Poor (Highly dependent on manual compound mixing ratios) |
| Pre-treatment Conditioning | Full (Vacuum defoaming, active agitation, jacket heating) | None (Resin condition shifts with room climate humidity) |
| Industrial Plant Housekeeping | Perfect (Zero styrene emissions, automatic solvent flush) | Hazardous (High VOC gas odor, requires heavy manual cleanup) |
Answer: Polyurethane (PU) and fast-curing epoxy resins exhibit an exceptionally short pot life and high reactivity once cross-linked with hardening agents. Traditional open resin baths cause rapid polymer gelation, heavy styrene VOC emissions, and massive material waste. Our automated two-component resin injection machine isolates the resin (Part A) and hardener (Part B) inside dual 60L sealed tanks. By utilizing localized continuous inline static mixing tubes, the compound is blended and injected directly into the closed pultrusion die cavity in real time, keeping the mixture fresh and maximizing fiber wet-out fluidity.
Answer: Any minor deviation in the specified resin-to-hardener ratio (such as a 100:30 displacement mismatch) triggers incomplete chemical cross-linking, compromising the tensile modulus of the final composite profiles. Zhongsheng's high-precision resin injection machine deploys dual imported metering pumps machined from ultra-hard Cr12MoV die steel, delivering a precise displacement matrix of 1.2 cc/rev. Coupled with independent closed-loop servo-motor drives, the master PLC micro-adjusts the volumetric feed rate (50-1200 ml/min) to sync with active gantry traction speed, keeping dosing tolerance within ≤±1%.
Answer: Raw thermosetting liquids require strict conditioning to eliminate micro-void defects. The Part A and Part B tanks on our 100KN-line injection equipment each hold 60L and integrate independent motorized agitators (380V, 120W) to prevent mineral filler sedimentation. Additionally, the tanks support fully integrated vacuum defoaming to strip out micro air bubbles before the compound enters the high-pressure 1/4" hoses, ensuring maximum laminate density for heavy structural section shapes.
Answer: Because the static mixer tube contains actively blended polymer adhesives, leaving the machine idle without purging would cause total internal hardening, destroying the gun head and block assemblies. Our HMI touch-screen control system features an automated, fast-track cleaning program. Upon production completion, the machine triggers an automatic air-and-solvent alternating purging cycle. This pneumatic system uses high-pressure air (0.5-0.7 MPa) to blow out remaining resin, followed by a targeted solvent flush that cleans the flow ports, ensuring the machine is immediately market-ready for the next shift.
Answer: Yes. Different profile widths and matrix thicknesses dictate different daily glue consumption volumes. The central HMI touchscreen interface allows operators to adjust the continuous volumetric flow boundaries arbitrarily between 50 to 1200 ml/min. Furthermore, if your factory footprint scales up to massive structural sheet piling or complex multi-cavity dies, Zhongsheng's in-house engineering facility can retrofit the pump assembly to higher displacement metrics and install optional inline heating jackets for the delivery hoses to lower high-viscosity resin resistance.
