BUILT INTO EVERY MODEL
Key features of the vertical LSR injection molding machine
Six characteristics that define how the TYM-L machines run on the production floor.
Vertical clamping
Direct-pressure hydraulic clamp opens upand down - ideal for placing inserts andrunning overmolding work.
Dual slide plate, dual station
One upper mold over two lower molds. Load one station while the other cures to raise output per shift.
Integrated control
Clamp, injection, and metering run from onecontroller, so setup and parameter changesstay in a single interface.
Dynamic mixing + direct-pressurebarrel
A and B components meter at 1:1 and blendthrough a dynamic mixer for a consistent,repeatable shot.
Guide-rail slide plate
Rail-guided table moves the molds quicklyand repeatably, with long service life undercontinuous use.
Fully enclosed frame
A closed, rigid body keeps the structurestable and contains the working area duringproduction.
DOSING & INJECTION
How the LSR molding system works
Two-component liquid silicone moves from drum to cured part in one continuous, metered path.
Feeding
Components A and B are supplied from the feed drums into the system.

From Raw LSR to Finished Part - Every Stage, Visible
Watch TYM's 8-cavity toothbrush molding line in operation: precision LSR dosing, closed-mold injection, full vulcanization, and clean automated demolding - all within a single continuous cycle.
Parts exit flash-free and dimensionally consistent, meeting the tight tolerances required for food-contact and personal care applications.
This is what a purpose-built LSR production line looks like when mold, machine, and automation are engineered together.

QUESTIONS
Frequently asked questions
When should I choose a vertical LSR machine over a horizontal one?
Choose a vertical LSR injection molding machine for overmolding or insert molding - for example bonding silicone onto glass, metal, or electronic inserts. A vertical clamp keeps the cavity facing up so inserts rest flat and stay located while the mold closes. A horizontal machine is usually preferred for high-volume, single-material parts with automatic ejection.
What clamping force do I need for my LSR molding project?
Clamping force depends on the projected area of the part and the injection pressure; larger or multi-cavity tooling needs more tonnage. The TYM-L series spans 95 T to 250 T. Share your part drawing and cavity layout and an engineer can recommend the right model.
Can I run two-station production on one TYM-L machine?
Yes. The dual slide plate mounts one upper mold over two lower molds. With two-station operation, an operator loads or unloads one station while the other cures, keeping the injection unit working and raising output per cycle.
Is the shot volume fixed on TYM-L series machines?
No. Shot volume is configured per order from 10, 35, 70, 160, or 285 g, so the barrel is matched to your part weight rather than oversized, for optimal material usage and cost efficiency.
Can TYM-L machines process medical or food-contact grade silicone?
Yes. The series is configured to run medical- and food-contact-grade LSR. Material certifications such as FDA and USP Class VI apply to the silicone compound; TYM manufactures under ISO 9001 and ISO 13485 quality management systems.
Do you supply molds and complete production lines as well?
Yes. Beyond the injection molding machine, TYM provides precision cold-runner LSR molds, OEM silicone parts, and turnkey automation lines, so the machine, tooling, and downstream automation can be specified and integrated together.
