Specialist Tools and Equipment for Textiles and Electronic Systems

This lesson covers the specialist tools and equipment used when working with textiles and electronic systems, as required by AQA GCSE Design and Technology (8552), Section 3.2.8. Both material areas have unique tools and processes that you need to understand for the exam.

Tools for Working with Textiles

Measuring and Marking Out

Tool	Use
Tape measure	Measuring body dimensions and fabric lengths (flexible, 150 cm)
Pattern paper	Creating full-size pattern pieces from a design
Tailor's chalk	Marking cutting lines and seam allowances on fabric (brushes off easily)
Fabric scissors	Cutting fabric accurately (dedicated to fabric to maintain sharpness)
Pinking shears	Cutting fabric with a zigzag edge to reduce fraying
Seam ripper	Removing stitches without damaging the fabric
Pins and pin cushion	Temporarily holding pattern pieces to fabric, or fabric layers together

Cutting Tools

Tool	Use	Scale
Dressmaking scissors	General fabric cutting by hand	One-off and small batch
Rotary cutter	Cutting straight lines through multiple fabric layers	Small to medium batch
Die cutter / clicker press	Cutting identical shapes from fabric using a metal die	Large batch and mass production
Laser cutter	Precision cutting of synthetic fabrics (seals edges)	Batch and mass production
CAM cutting table	Computer-controlled multi-layer cutting using a blade or laser	Mass production (e.g. Gerber cutter)

AQA Exam Tip: Questions often link tools to scales of production. A laser cutter or CAM cutting table is appropriate for mass production, while dressmaking scissors and pins are used for one-off production. Be ready to justify your choice.

Sewing and Construction Tools

Tool/Equipment	Use
Sewing machine	Joining fabric with a lockstitch — faster and stronger than hand sewing
Overlocker (serger)	Trimming and enclosing raw edges with an overlocking stitch to prevent fraying
Embroidery machine (CAM)	Stitching decorative patterns automatically from a digital design
Iron and ironing board	Pressing seams open, applying interfacing, preparing fabric
Fusible web (Bondaweb)	Bonding fabric layers together using heat (iron-on appliqué)

Textile Finishing Equipment

• Heat press — applies heat-transfer vinyl or sublimation prints to fabric at a controlled temperature and pressure. Used for custom t-shirts, sportswear and promotional products.
• Screen printing equipment — screen, squeegee, emulsion, ink — used for printing designs on fabric.

Tools for Working with Electronic Systems

Measuring and Testing Tools

Tool	Use
Multimeter	Measuring voltage, current and resistance in a circuit
Oscilloscope	Displaying waveforms to analyse signal frequency and amplitude
Logic probe	Testing whether a point in a digital circuit is HIGH (1) or LOW (0)
LDR, thermistor, potentiometer	Input components used for sensing light, temperature and position
