Let’s give you some insight how Norck manufactures bridge tooling and injection molding.

There are mainly three toolings used for injection molding projects: prototype, bridge, and production tooling.

Bridge tooling is used for the phase between prototyping and production tooling to produce a medium-volume of a part or product. Its purpose is to provide components to start the assembly processes while waiting for the production tooling for mass production or to test the market.

The mold is made from mild-grade steel and has missing features like a cooling system, which reduces its cost compared to production tooling.

Bridge tooling offers many advantages:

• Cost effective: Cost is reduced due to the mold material (mild steel)

• Accurate parts: Bridge molds are more accurate than prototype tooling, which will reduce deficiencies.

• Fast to manufacture tooling: Since the mold is missing features and the used material is mild, bridge tooling can be manufactured faster than production tooling, which helps start the assembly process while waiting for the manufacturing of the production tooling.

• Well adapted for medium-volume production.

But there are some disadvantages as well:

   - Mild material: will wear if the molded plastic is rigid or has fiberglass in it.

Bridge injection molding mold is made through four steps:

1. Plastification: The plastic granules are transferred from the hopper to the mold using a rotating screw and molted using heaters.

2. Injection: The plastic granules are transferred from the hopper to the mold using a rotating screw and molted using heaters.close until the plastic solidifies.

3. Cooling: After injection, the molted plastic will be cooled down to become solid using a cooling circuit. The screw will hold its position to hold the pressure inside the mold.

4. Ejection: After the molted plastic solidifies using a cooling circuit, the Die is opened, and the part is ejected via ejector pins. The screws will retreat to prepare for the next injection.

Obtaining a fully functional part might require extra processing for features that can’t be made with the Bridge tooling process, such as taping. The designed part should follow Bridge tooling design guidelines.
