acrylic fabricator Interview Questions and Answers

1. What experience do you have with acrylic fabrication?

   • Answer: I have [Number] years of experience working with acrylic, encompassing [List specific tasks like cutting, shaping, polishing, bonding, etc.]. I've worked on projects ranging from [Size/Scale of small projects] to [Size/Scale of large projects], and am familiar with various acrylic types and thicknesses. My experience includes [Mention any specific techniques or equipment used, e.g., CNC machining, thermoforming, laser cutting].

2. Describe your experience with different acrylic sheet thicknesses.

   • Answer: I've worked with acrylic sheets ranging from thin gauge (e.g., 1/8") for delicate applications like displays to thicker gauges (e.g., 1") for robust structures. I understand the different machining and handling techniques required for each thickness, and I know how to choose the appropriate thickness based on project requirements and anticipated stresses.

3. What are the different types of acrylic you are familiar with?

   • Answer: I'm familiar with cast acrylic (like Plexiglas or Lucite) and extruded acrylic. I understand the differences in their properties, such as clarity, impact resistance, and machinability. I also have experience with coloured, frosted, and patterned acrylics.

4. How do you ensure the accuracy of cuts and shapes when working with acrylic?

   • Answer: Accuracy is paramount. I use precise measuring tools, such as calipers and rulers, to ensure accurate measurements before cutting. I utilize [Specific cutting methods, e.g., laser cutting, CNC router, table saw] that offer high precision. I also regularly check my work during the process and use appropriate jigs and fixtures to maintain accuracy.

5. What safety precautions do you take when working with acrylic?

   • Answer: Safety is my top priority. I always wear appropriate personal protective equipment (PPE), including safety glasses, gloves, and dust masks. I'm aware of the potential hazards of acrylic dust and fumes and take precautions to minimize exposure. I follow all safety regulations and procedures related to the machinery and tools I use.

6. Explain your experience with polishing and finishing acrylic.

   • Answer: I have extensive experience in polishing acrylic to achieve a high-gloss finish. I use progressively finer grits of sandpaper and polishing compounds to remove scratches and imperfections. I'm also familiar with techniques for achieving various finishes, such as matte or satin finishes. I pay close attention to detail to ensure a flawless and consistent finish.

7. How do you bond acrylic sheets together? What adhesives do you prefer and why?

   • Answer: I use a variety of methods for bonding acrylic, including solvent welding, using specialized acrylic adhesives, and mechanical fasteners (in certain cases). I prefer solvent welding for its strength and invisible seams, especially for creating seamless joints. However, I understand when other methods are more appropriate. My choice depends on the project’s specific needs and the desired aesthetic.

8. How do you handle imperfections or mistakes during fabrication?

   • Answer: I strive for perfection, but mistakes can happen. If I find an imperfection, I carefully assess the severity and feasibility of correction. Minor imperfections might be addressed through polishing or sanding. More significant errors might require re-cutting or even starting the piece over, depending on the project's scope and the extent of the damage.

9. Describe your experience with CNC machining of acrylic.

   • Answer: I am proficient in using CNC machines to fabricate acrylic. I can program and operate CNC routers and mills to create complex shapes and designs with high precision. I understand the importance of proper tooling and feed rates to avoid damage to the material. I am also experienced in using CAM software for generating CNC toolpaths.
