Die and Mould
Hot stamping dies, press platens and mould preheat, where the heater lives inside the tool.
The tool is expensive, the bores are already machined, and the heater has to fit them exactly.
The process, and where the heat goes in
Read left to right. Each block is a place on the machine that has to be held at a temperature, coloured by how hot it runs.

Zone by zone
This table is the whole argument for the page. It maps the machine you already have to the element type that suits each position on it, and every product name links to the family page with the sizes, the options and the codes.
| Zone | Duty | Typical temperature | Swiftheat product | Why this element |
|---|---|---|---|---|
| Press platens | Embedded, continuous | 100 to 300 °C | Cartridge Heaters | Bore mounted across the platen, wattage distributed to keep the face even |
| Hot stamping and forming dies | Embedded, cyclic | 120 to 300 °C | Cartridge Heaters | Small diameter cartridges close to the working face |
| Mould preheat | Embedded or clamped | 40 to 200 °C | Cartridge Heaters | Cartridges in the bolster, or strip heaters on the flat |
| Tool face plates | Flat surface | 100 to 250 °C | Strip Heaters | Clamped to a machined face, hole pattern to your drawing |
| Control loop | Measurement | - | Thermocouples and Temperature Sensors | Sensor bores are usually already in the tool, so the diameter is fixed |
Temperatures are typical for the process and are given as a starting point. Send us the zone temperatures your machine actually runs at and we will work back to a safe loading.
Products for die and mould
A shortlist, not the whole catalogue.
-
Cartridge Heaters
Bore mounted in moulds, platens and dies. Round, swaged, made to your length.
-
Strip Heaters
Flat and gently curved surfaces, sealing bars, platens and duct air.
-
Tubular Heaters
Air, liquids and surfaces. Straight, U form, W form or coiled to your drawing.
-
Thermocouples and Temperature Sensors
Types J, K, N, T, E, R, S, B and C, plus PT100, PT500 and PT1000 RTDs, made to length.
Application notes
The bore is already there, so the heater is made to it
In tool work the hole exists before the heater does. Send the bore diameter with its tolerance and the depth. We size the heater to that fit, which is the single biggest lever on how long it will last.
Distributed wattage across a platen
A platen heated by identical cartridges is hotter in the middle, because the edges lose heat. Uneven wattage along the heater, or a different wattage in the edge bores, evens the face out. Tell us the platen size and how flat the face has to be.
Removal matters as much as installation
A cartridge that has run for a year in a mould can seize in the bore. A removal aid, or a sacrificial anti seize on assembly, turns a two hour job into a five minute one. Ask for it when the tool is expected to be serviced in place.
What to send us
An enquiry with these in it can be quoted the same day. An enquiry without them takes three phone calls first.
- Tool type and the process it runs
- Bore diameter, tolerance and depth for every heated position
- Number of bores and their layout across the tool
- Working temperature and how flat the face has to be
- Whether the tool is serviced in place
- Sensor bore diameter and depth
A photograph of the old element next to a tape measure is worth more than a paragraph of description, and a drawing is worth more than both.
Build the list instead
If you are replacing several elements at once, the list builder walks through each one, draws it as you specify it, and produces a single printable document you can send by email or on WhatsApp.
