Product Description
The four column hydraulic press features a welded steel frame with high rigidity and good anti-deformation performance. Four columns guide the ram for precise positioning and consistent processing. The hydraulic system is adjustable and easy to operate, with built-in safety protection. Sealing is good, energy use is low, maintenance cost is low, and installation is quick.

Product Advantages
Welded frame with stress-relief annealing resists deformation under full load.
01
Four-column guiding gives better ram parallelism than frame‑type presses.
02
Lower energy draw and less frequent seal replacement than older designs.
03
Quick installation - no special foundation needed for most sizes.

Main Applications
This four column hydraulic press is a core machine for FRP compression molding. It uses preset heat, pressure, and hold cycles to cure SMC, BMC, DMC, and GMT compounds. Parts come out with high strength, tight dimensions, and good surface finish. It serves civil, industrial, and municipal sectors. This equipment is also referred to as a 4 column hydraulic press, four column hydraulic press machine, or four pillar type hydraulic press.
Frequently Asked Questions (FAQ)
Q: Can the same press handle both small test molds and large production molds?
A: Yes. The control system stores multiple mold recipes. You can adjust pressure, stroke, and hold time for each job. Changeover between molds takes about 15–30 minutes.
Q: How do you ensure the four columns stay parallel after years of use?
A: The columns are induction‑hardened and chrome‑plated. The ram has adjustable bronze bushings. We recommend a parallelism check every 2000 hours. If needed, bushing shims can be adjusted on site.
