1. Right Angle Block Cartridge Heater for Tight Spaces
In compact injection molds and automation machinery, cable clearance is often a major challenge. The Hongtai Right Angle Cartridge Heater solves this by using a stainless steel block to exit the lead wires at a precise 90-degree angle.
Unlike bending standard leads (which often causes internal short circuits), our 90 degree heater leads are mechanically protected inside a rigid metal block welded to the sheath. This design allows the heater to be installed flush against mold walls or in limited headroom applications without risking wire breakage or exposure.

2. Key Technical Features
-
Space Saving: Requires only 10-15mm of clearance above the heater hole.
-
Lead Protection: The stainless steel block eliminates stress on the crimp connection, preventing “pull-out” failures.
-
Robust Design: TIG welded block ensures the transition is sealed and durable.
-
Versatile Orientation: The block can be aligned to any specific rotation angle relative to the heater if required.
-
High Temp Options: Available with fiberglass or ceramic bead insulation for high-temperature environments.

4. Industrial Applications
This compact heating element is the ideal solution for:
-
Injection Molding: Manifolds and nozzle heaters where wires must run parallel to the mold plate.
-
Packaging Machines: Sealing jaws where vertical clearance is restricted by moving parts.
-
Medical Equipment: Compact fluid heating chambers inside analytical devices.
-
Semiconductor: Vacuum chambers with limited pass-through space.
5. Why use a “Block” instead of a bent wire?
Bending a standard heater’s wires sharply at the exit point puts mechanical stress on the internal connection pin. Over time, thermal expansion and vibration will snap the wire.
The Right Angle Cartridge Heater block moves this stress point away from the connection. The wires exit safely through the side of the block, ensuring the internal connection remains straight and secure, significantly extending the heater’s life in tight installations.
6. FAQ
Q: What are the dimensions of the block?
A: The block is typically slightly larger than the heater diameter (e.g., for a 10mm heater, the block is approx 12x12mm). We can provide a detailed CAD drawing for your clearance check.
Q: Can I get armor (hose) protection on the right angle leads?
A: Yes. We can weld a stainless steel flexible conduit directly into the 90-degree block. This offers the ultimate protection against abrasion and crushing in automation environments.
