Mold Qualification, Evaluation, Testing

Whether you are having a problem with a mold or just need to confirm a mold is working properly, Janler has been troubleshooting plastic molds for over half a century.

Our extensive mold manufacturing history coupled with our expertise in injection molding puts Janler in a position to effectively and efficiently qualify and evaluate injection molds.


Mold sampling, qualification and capability studies are but a few of the services offered by Janler. Whether you have a mold that you would like debugged or you have ordered a mold from Janler, all molds are tested on our injection molding machinery prior to leaving our facilities to make sure that the mold and the molded parts meet the specifications and requirements of any project.

Many times, customer’s plans change and they may not be able to start a molding as soon as anticipated, but parts are still needed to fulfill requirements. Janler is accustomed to pre-production runs to fill in the gaps in production.

Janler has been running 24-hour plastic injection molding facilities for over half a century and is well equipped to handle high-volume production runs as well. With a full-service molding department that collaborates closely with our mold making department, we are well positioned to offer complete injection molding services.

Assembly/Post-Molding Services

Complementing our full–service molding department, Janler offers a number of post-molding services:

  • Sub-assembly and assembly
  • Machining
  • Sonic welding
  • Hot stamping
  • Custom packaging
  • Part separators and conveyors

Transfer Tooling

Do you have a product that needs molding and already have molds? We offer short to long run options at our facility.

All tooling transfers start with timely and effective communication. Accurate information needs to be collected before action is taken so all parties involved can plan and coordinate. This includes providing tooling details such as a description of the molds to be transferred, their value, weight, size, design, quantity, used life span, packaging, and pictures. The ship date, consignee, destination, and other logistical information will then be confirmed.
