The vertically integrated advantage

Engineering, tooling and production work as one system.

Difficult molding programs often fail between disciplines. PlastiCert keeps the analysis, tool decisions, process development and validation connected under one roof.

1

Understand the requirementPart function, program history, material, measurement and release needs.
2

Analyze the riskDFM, mold flow, tooling condition and root-cause investigation.
3

Execute the approved planTool work, fixture development, process setup and controlled sampling.
4

Validate for productionMeasurement alignment, qualification evidence and production readiness.

Experience at the press

Complex inserts require more than a capable machine.

PlastiCert operators understand the placement, pace and discipline required to keep insert molding cycles moving. When a program calls for it, our team designs practical loading fixtures that support repeatability without forcing unnecessary automation.

Direct answers

Common questions about working with PlastiCert

Can PlastiCert take over an existing injection mold?

Yes. The mold-transfer process begins with documentation and inspection, followed by recommendations, approved repairs or modifications, controlled sampling and production validation.

Does PlastiCert help with product design?

PlastiCert does not provide complete product design in-house, but supports design for manufacturability, material-performance decisions, mold-flow analysis and molding feasibility.

What production volumes are the best fit?

PlastiCert is strongest in recurring, complex production programs. Requirements around 2,000-5,000 parts per month are often a good fit, depending on part size and complexity.

Where is PlastiCert located?

PlastiCert is located in Lewiston, Minnesota, near customers throughout Minnesota, Wisconsin and Iowa while supporting demanding OEM programs across the United States.
