How It Works

How the 8-Ton LSR Molding Press Works

The MB-8 is a silicone molding machine built around a pneumatic heated-platen press, not an adapted injection unit. Clamping force is generated pneumatically at 100 psi, closing the platens with 8 tons of force in as little as one second per inch of stroke. Heated platens hold a consistent cure temperature across the full 6-inch stroke, so parts cure evenly from the first shot to the last.

Because this molding press has no hydraulics and no injection unit, there's less to maintain and a simpler qualification package for cleanroom environments. MonoBiologics manufactures the MB-8 in-house as part of a complete LSR metering, mixing and molding platform — pair this silicone molding machine with the Benchtop or Production LSR Metering & Mixing System for a complete molding cell, from metering and mixing through to a finished, cured part.

Why This Press

Fast, simple, cleanroom-ready molding

A cleanroom-ready molding press purpose-built for silicone overmolding, not adapted from an injection platform.

⚡

Fast clamp speed

1 in./sec clamp speed for short cycle times.

💧

No hydraulics

Fully pneumatic, with simpler maintenance and no oil system to service.

⚙

No injection unit

Fewer wear parts and a simpler qualification package.

🌡

Heated platens

Consistent cure across the cycle.

📏

Compact footprint

36 in. x 20 in. x 60 in. relative to 8 tons of clamping force.

⚖

Pairs with either meter/mix system

Complete the platform with the benchtop or production system.

Where the press is used

Silicone tubing & connector overmolding

Fast-cycle molding for high-volume components.

Medical device component molding

Cleanroom-ready cycles for device manufacture.

Compression & transfer molding

Silicone and polymer parts on a fixed-cycle press.

Cleanroom-ready molding operations

No hydraulics to contaminate a controlled environment.

Low-to-mid volume production runs

Right-sized for programs that do not need a full injection platform.

In-house overmolding programs

Bring molding capacity in-house alongside your meter/mix system.

Need metering and mixing before molding?

Pair this press with the Benchtop or Production LSR Metering & Mixing System.

FAQ

8-Ton LSR Molding Press FAQ

Does the press include an injection unit?

No. The MB-8 is a pneumatic heated-platen press only, with no injection unit.

Is the MB-8 a compression molding machine or an injection molding machine?

Neither exactly. The MB-8 is a pneumatic compression and transfer molding press — it has no injection unit, so it is not an injection molding machine. It is purpose-built as a silicone molding machine for overmolding and compression molding work.

What is the clamping force?

8 tons.

What air supply is required?

100 psi.

What is the clamp speed and stroke?

1 in./sec clamp speed with a 6 in. stroke.

What are the dimensions and weight?

36 in. x 20 in. x 60 in., 600 lbs.

Does it use hydraulics?

No, the press is fully pneumatic.

Can it be paired with a meter/mix system?

Yes, either the benchtop or production system.

Is it suitable for cleanroom use?

Yes, the design is cleanroom-ready with no hydraulic oil system.
