Frequently Asked Questions

What sets you apart from other chemical etching companies?

---

We combine decades of expertise, cutting-edge technology, a fully automated production line, rapid delivery services, and dedicated customer support. Our standard lead-time is five business days with expedited services available for urgent requirements. We also don’t have a minimum order quantity and support low-volume and one-off orders as well as large production runs.

Do you offer expedited services, such as rapid prototyping or 48-hour delivery?

---

Yes, we provide a 24 and a 48-Hour Rapid Delivery service for prototype flat components. With no minimum order quantity and support for low-volume orders, we’re a perfect option for operations of all sizes.

Do you offer global shipping and support?

---

Yes, we ship worldwide and provide dedicated account managers to assist customers globally.

How accurate is the process? (What are the tolerances achievable?)

---

Depending on your requirement we can achieve a minimum working tolerance of +/- 10% of metal thickness or +/- 0.025mm, whichever is greater.

Do you have any quality assurances in place?

---

We use advanced inspection tools and adhere to rigorous quality control standards to ensure every part meets specifications. We’re ISO-9001 certified and comply with specific certifications for industries like aerospace and medical. And, with processes that have been refined over the years and an automated production line, we deliver consistent quality regardless of batch size.

How small can apertures, holes, bars etc be?

---

Generally all detail must be equal to a minimum of 0.1mm, however this can be improved upon depending on your requirement.  Please contact us to find out.

What file formats do you accept for designs?

---

We accept CAD files in formats such as DXF, DWG, and STEP. Contact us if you have another format.

Can you help with design modifications or optimisation?

---

Yes, our engineers work with you to ensure your design is optimised for chemical etching, improving quality and cost-effectiveness.

Are there any design limitations?

---

While chemical etching is versatile, there are limits based on material thickness and etch depth. For example, fine details may require thinner materials.

How fast can you manufacture prototypes?

---

We look at each part required, and give a realistic lead-time to meet the customer’s requirement. Depending on production schedules, prototypes can be turned around within 48 hours.

How is the cost of chemical etching determined?

---

Costs depend on factors like material, part complexity, quantity, and any additional processes required. Unlike traditional methods, chemical etching uses digital tooling, which is included in the setup cost and can be easily modified for a small charge. We also provide volume discounts for larger orders.

What is the PCGT charge for?

---

PCGT stands for Part Cost Graphic Tooling and refers to the photo-tool that is required to make any part. We only ask you to pay a portion of the cost. We will then not allow anyone to order or ask for a quote that involves using your tooling, without your written permission.

Can you make a mixed sheet of parts?

---

Yes! This can be done, but a) only if all parts are to be made from the same thickness and type of material, and b) if all parts are to be ordered in similar quantities at the same time in the future. Contact us for further information, telephone 01480 226699.

When do we use tabs to hold parts in sheet form?

---

When the parts are very small, and made from thin material, to stop them ‘flying away’ when in contact with jets of acid. Tabs are also used when a part is being plated after etching, as it is much more cost effective to plate a sheet of parts than individual parts.

What metals can be cut using the Laser cutting service?

---

Virtually any metal can be laser cut ranging in thickness depending on metal type.

Can you include both the Chemical Milling and Laser Cutting process on the same piece of metal?

---

Yes, for example Photofab can etch detail into the surface of the metal, and then laser cut the profile.

Does the gas used when laser cutting make a difference?

---

Yes it does, by changing the gases we can produce an edge finish on stainless steel as clean as the natural material. This is especially useful in medical and aerospace requirements.

Is chemical etching environmentally friendly?

---

Yes, chemical etching produces minimal waste, and we use advanced filtration systems to recycle and reduce environmental impact.

How do you handle waste and ensure compliance with environmental regulations?

---

We adhere to strict environmental regulations, recycling chemicals where possible and disposing of waste safely and responsibly.

What additional services can you offer?

---

Forming, plating/coating, heat-treating, painting, in-filling, screen-printing, soldering, stud welding or drilling holes.
