ML-L1A is a specialized automatic hot mounting press for metallographic specimen preparation, known for its user-friendly operation, adjustable supplementary pressure, and threaded locking feature. This hot mounting press offers a wide range of configuration options, allowing users to adjust supplementary pressure, heating temperature, cooling temperature, heating time, and cooling time based on sample materials, embedding resin types, preparation requirements, and metallographic inspection demands. This flexibility ensures the quality of sample preparation.
The ML-L1A machine provides excellent support for laboratories and production lines involved in metallographic specimen preparation, material analysis, hardness testing, and other related experiments.
Features
HMI Interface
Compensating pressure, heating temperature, cooling temperature, heating time and cooling time can be set.

Easy Operation
One-touch activates the machine with all functions of auto pressure adding, auto heating, and auto cooling, which is easy to be operated by inexperienced users.
Adjustable Compensating Pressure
High-temperature resistance but without high-pressure resistance samples can be prepared through a customized program. It increases the flexibility of the preparation.
Acrylic Powder
Besides the bakelite powder, the acrylic powder can be also used. The acrylic powder can be applied for producing a highly transparent specimen with good edge retention.

Filter Assembly
The water filter assembly effectively filters minerals and impurities in the water, ensuring smooth water flow and prolonging the lifespan of the water valve.
Special Bracket for Handle
Thread-locking cover can be put on the special bracket. This increase a space efficiency.

Memory Mode
30 sets memory mode can memorize different parameters, which is easy for the users to opt for. The sets of memory mode can be also customized.

Cooling Temperature Setting
The cooling temperature can be set from 10°C to 100°C according to the requirement. Samples can be taken out earlier than the normal parameter setting. Preparation time can be greatly shortened by applying a pre-heat mode.
Lower Ram with Chamfering Design
Chamfering design can avoid the waste or the damage of SiC paper or polishing cloth during the grinding/polishing process.
Thread-Locking Cover
It significantly increases the top cover's strength, preventing damage to the mold tube or top cover caused by improper operation.

Electric heating device and hydraulic design
An electric heating device can increase the temperature quickly and stably. A hydraulic pressure compensation design is also stable.
Spacer (option)
With a spacer, the user can mount two specimens at the same time. It will greatly reduce the sample preparation time.
