Assembly & secondary operationsMount Vernon, Indiana

Assembly and secondary operations deliver production-ready plastic components

Infinity connects molding to assembly, marking, joining, inspection, and final pack so each added operation supports the same program requirements.

One manufacturing pathInteractive operation planner

A planned secondary-operations path keeps every handoff aligned to the finished component

Choose an operation to explore how the molded part, fixture, process, and acceptance requirements can be considered as one connected program.

01Selected operation
Fit + join

Build repeatable assemblies around the component

Program-specific fixtures, work sequence, and component orientation can help turn molded parts into consistent subassemblies or finished assemblies.

  • Plan access around critical features and surfaces
  • Define the sequence before production launch
  • Connect acceptance checks to the completed work

Value-added capability deckJoin / identify / finish

Assembly and secondary operations turn molded parts into production-ready products

Infinity can coordinate the secondary work a program needs without disconnecting it from molding, quality, or delivery expectations.

Assembly + subassembly

Bring multiple components into one controlled build

Minor assembly, subassembly, and full assembly can be planned around the part geometry and program requirements.

Insert molding

Integrate an insert into the molded component

Coordinate insert presentation, tooling access, material flow, and finished-part handling as one molding strategy.

Custom laser marking

Add durable, program-specific identification

Laser marking can support identification and information needs while staying connected to the downstream production flow.

Pad printing

Apply visual information and decoration with control

Pad printing can be integrated for product graphics, indicators, or other defined visual requirements.

Ultrasonic welding

Join compatible plastic components into a unified assembly

Ultrasonic welding adds a repeatable joining option when the component design, materials, and performance intent align.

Final pack + fulfillment

Protect completed work through the final handoff

Final packaging, kitting, and fulfillment can be matched to the product and delivery requirements of the program.

Connected production handoffFive controlled decisions

A controlled production handoff protects each molded component through final release

The right secondary process is only part of the solution. How parts arrive, move, remain protected, and leave each operation matters just as much.

  1. 01
    Mold

    Establish the component

    Begin with a repeatable molding process and the part requirements that govern every downstream step.

  2. 02
    Present

    Control orientation

    Move and fixture the part so the next operation reaches the intended feature without avoidable surface risk.

  3. 03
    Add value

    Perform the operation

    Assemble, mark, print, weld, or pack within a sequence designed around the program.

  4. 04
    Verify

    Check the result

    Connect inspection decisions to the feature, assembly, or finished condition that matters.

  5. 05
    Release

    Protect the handoff

    Maintain part identity and protection as finished work moves to packing, fulfillment, or the customer.

Quality at every handoffEvidence stays connected

Inspection and documentation keep assembly decisions connected to the quality plan

Infinity's CMM, electronic vision, inspection, and validation capabilities help teams define what must be checked before, during, and after value-added work.

IN
Before the operation

Confirm the input

Part condition, orientation, material identity, and supplied components establish the starting point.

IP
In process

Monitor the critical result

Program-defined checks can evaluate presence, position, appearance, or another agreed requirement.

OUT
Final handoff

Release with evidence

Finished assemblies move forward under the applicable inspection and documentation plan.

Technology + talentRepeatable work / skilled decisions

Automation manages repeatable motion while skilled teams protect process judgment

Robotics can present, orient, transfer, and route components. Experienced people remain essential for changeovers, exceptions, problem-solving, and continuous improvement.
