Injection molding hydraulic press cylinder repair procedure:
1: Complete disassembly and cleaning for visual inspection and precision measurements.
2: Inspect rod and check whether its chrome or thermal spray and strip all coatings to bare base metal. Check the rod and barrel with dye penetrant for any cracks, pits, chips, scars, etc.
3: Repair any deep scars, pits, dings with welding and blend in with belt sanding and high speed hand tools. Blend in 100% clean up and check with dye penetrant again.
4: Precision OD grind cylinder rod to 100% clean up.
5: Inspect barrel and repair any deep pits or damage with welding and blend in perfectly.
6: Precision hone barrel to 100% clean up
7: Chrome plate the OD of the cylinder rod oversize or Thermal spray coating oversize. If it has hard chrome, we will use hard chrome, if it’s thermal spray, we will use a higher strength material for a more durable and longer lasting surface that will resist pitting, chips, scars, etc.
8: Precision OD grind rod to original size. Polish finished rod to bright/smooth finish
9: Install new packing and seals and assemble hydraulic press cylinder.
10: Complete pressure test and run for 30 to 40 cycles (open and close under medium and high load) and check for smooth operation and leaks. Final testing takes 24 hours under light, medium and high loads, checking for holding & maintaining pressure, leaks, smooth operation, speed of operation, etc. We make sure your hydraulic press cylinder is working like new.
11: Paint or powder coat to OEM color and prepare for shipping in custom crate with foam packaging and metal banding.
The end result is an injection molding hydraulic press cylinder repair that will perform like new in 10 days or less with a 12 to 24 month warranty. All while saving 50 to 80% of replacement cost.
