Key features of the TYM-Y LSR injection molding machine
Six characteristics that define how the TYM-Y machine run on the production floor.
Toggle (knuckle) clamping mechanism
A mechanical toggle linkage multiplies clamping force, delivering 170–280 T from a compact frame and locking the mold securely throughout the cure.
Energy-efficient force holding
Once the toggle locks, clamping force is held mechanically rather than hydraulically, reducing power draw during the curing phase for lower running costs.

High clamping force range
The 170 T / 230 T / 280 T lineup suits larger projected areas, multi-cavity molds and higher-pressure LSR parts beyond the direct-pressure series' reach.
Long opening stroke
Opening strokes from 180 up to 1140 mm accommodate tall parts, deep cavities and automated demolding clearance.
Integrated intelligent control with NOVO ruler
A centralized control platform with German NOVO electronic position sensing and TYM's proprietary software ensures precise, repeatable clamping, injection and ejection.
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.

>>
1:1 metering
A volumetric metering cylinder doses A and B at a fixed 1:1 ratio.
2
>>
Color dosing
A color pump injects pigment into the stream at the set rate.
3
>>
mixing
The mixing system blends A, B, and color into a uniform compound.
4
>>
Injection
The direct-pressure barrel injects the mixed silicone into the mold.
5
>>
Heat curing
The heated LSR mold cures the part to its final shape

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.
Typical applications
The higher clamping force and long stroke suit larger projected areas, multi-cavity molds and taller parts.

Frequently asked questions
What is the difference between the toggle and direct-pressure TYM-W machines?
The toggle (knuckle) series uses a mechanical clamping linkage that delivers higher clamping force (170–280 T) from a compact frame and holds force mechanically during cure, lowering energy use. The direct-pressure series (95–160 T) is optimized for fast, simple mold action on smaller parts.
What products can the TYM-W Toggle Series produce?
Larger and multi-cavity LSR parts such as automotive seals, baby pacifiers and nipples, menstrual cups, medical valves and stoppers, and deeper food-contact or industrial silicone components.
What does the model number mean?
The number encodes clamping force - TYM-W170 = 170 T, TYM-W230 = 230 T, TYM-W280 = 280 T - so you can match the machine to the projected area of your mold.
Why choose toggle clamping for LSR?
Toggle clamping provides high, stable holding force with lower hydraulic energy consumption during curing, which suits high-volume runs and larger molds where energy efficiency and force stability matter.
Can shot volume and stroke be customized?
Yes. Shot volume is customizable up to 450 g, and opening strokes (up to 1140 mm) and ranges can be further tailored to the part and mold.
Can the machine be integrated with automation?
Yes. The TYM-W Toggle Series supports robotic loading, automated demolding, vision inspection, and complete turnkey production lines.
