Industry Challenges

Bucket and container manufacturers face unique production hurdles:

Thin-wall parts that are difficult to fill and prone to warping, sizing, and lid fit

High aesthetic standards for consumer products

Cycle time pressure in high-volume runs

Fluctuating resin prices and material availability

Durability and performance expectations for industrial use

How RJG Helps:

We Make Difficult Parts, Easier to Mold

Our cavity pressure sensor technology and scientific molding methods let you:

• Confidently produce thin-walled or large parts with tight dimensional and structural requirements
• Solve warp, sink, bottom cracking, and short shot issues before they happen
• Rapidly troubleshoot and stabilize your process—even across multiple machines or facilities

Enable Use of Lower-Cost Materials Without Sacrificing Quality  

RJG’s real-time process control systems (like CoPilot® and iMFLUX®) allow you to:

• Absorb material variation automatically
• Optimize around recycled or lower-grade resins while maintaining consistent part quality
• Minimize over-packing, reducing stress and material use

Increase Uptime and Profit Margins  

Our solutions reduce your reliance on manual tweaks and floor supervision:

• Automatically detect and adjust for variation in viscosity, fill, and cooling
• Cut startup and changeover times
• Decrease scrap and rework rates
• Enable fewer operators to run more machines effectively

Real-World Impact

One container manufacturer using RJG technology saw dramatic improvements in just one job over a single month:

  • 4.7 Days of production time saved
  • $6,058 in material cost savings
  • $8,053 in labor cost savings
  • $6,713 in machine cost savings

That’s over $250,000 in annual savings from just one job.
