Electronics and electrical buyers increasingly specify thermoformed medical device trays instead of injection moulding or corrugated board. Here is where they are used and why they work.
The notes below come from day to day production and export work with overseas buyers.
This category covers a family of products rather than a single item. In practice a buyer defines thermoformed medical device trays by three things: the base resin, the format or dimension, and the performance or certification level it has to meet. Typical options in this category include sterilisation compatible grades; gauge 0.40 to 1.50 mm; gamma, ETO and steam options. Materials most often specified are Polyethylene Terephthalate, Polyethylene Terephthalate Glycol, Polycarbonate, Polystyrene, and the choice between them changes stiffness, temperature resistance, chemical behaviour and price.
In the electronics and electrical sector the decision is usually driven by ESD protection and dimensional accuracy, with cleanliness as a secondary requirement. Typical end uses include device inserts, accessory blisters, component trays.
Typical values for a general purpose grade are listed below; filled, stabilised and speciality compounds will differ.
| Material | Density | Tensile strength | Service temperature |
|---|---|---|---|
| Polypropylene | 0.90-0.91 g/cm³ | 25-40 MPa | -10°C to 100°C |
| Polycarbonate | 1.20 g/cm³ | 55-70 MPa | -40°C to 120°C |
| Polystyrene | 1.04-1.06 g/cm³ | 30-50 MPa | -20°C to 70°C |
Polyethylene Terephthalate is frequently the default selection here: High IV PET resin is the reason a 1.5 L bottle can be light yet hold carbonation pressure.
Typical electronics and electrical users specify this product for the following jobs.
Beyond the base resin, most suppliers offer UV stabilised, food contact, flame retardant, anti-static and recycled content versions of the same product. Ask which additive package is included, because it is often the difference between a part that lasts three years and one that lasts ten.
The route below is the one most factories use for this type of part.
Secondary operations such as printing, welding, machining and assembly are often cheaper to do in the same factory, and they reduce the risk of mismatch between components.
Use this checklist when comparing two or three supplier quotations.
Send this list to your supplier with the drawing and you will receive comparable quotations from every factory you contact.
For standard sizes and colours the minimum is usually one pallet or one production run; for custom tooling the economic minimum depends on the tooling cost amortised over the expected volume. Send us your annual volume and we will calculate the break even point.
Standard production tolerance follows the relevant ISO or DIN tolerance class for the process; tighter tolerances are possible after machining or grinding, but they add cost. Define the tolerance only on the functional dimensions.
Yes. {mat1} is one of our regular materials for this item, and we can supply virgin, modified and certified grades with full traceability. Material certificates and test reports are issued per batch.
A new tool typically takes 25 to 45 days depending on cavity count and complexity, followed by T1 samples within one week. Existing tools can usually start production within 10 to 15 days of order confirmation.
Yes. Standard samples are normally free of charge and shipped within three working days; custom samples are charged at cost and credited against the first production order.
Our team supplies thermoformed medical device trays to electronics and electrical customers worldwide, with samples, material certificates and full inspection reports available before mass production.
