What is Line Wire Bending?
Line Wire Bending and Hot Wire Bending is a fabrication process that involves precisely shaping plastic rods or wires into specific configurations using heat and specialist equipment. This technique enables the creation of strong, consistent, and uniform bends in plastic profiles without compromising the structural integrity of the material.
At Dipec, we provide high-quality Line Wire/Hot Wire Bending services for a wide range of plastic fabrication applications – offering accurate, repeatable results with custom bends to match your project requirements.

Line Wire Bending Process at Dipec
We begin by assessing your technical drawings and identifying which bends, angles, and plastic types are involved. This ensures we select the right tools and techniques from the outset.
Plastic sheets are marked and positioned according to bend lines. Accurate placement ensures consistent results across single units or batch production.
A heated wire or strip is applied to the bend line, softening the plastic at the precise location. Temperature and timing are carefully controlled based on the plastic type and thickness.
Once pliable, the plastic is bent manually or with a jig to the required angle. We hold each bend until the material sets, ensuring sharp, clean results without distortion or bubbling.
The part is cooled in place to fix the shape. We inspect the bend for clarity, smoothness, and dimensional accuracy – then move onto assembly or further fabrication if needed.

Line Wire Bending FAQs
Line Wire Bending is a specialist plastic fabrication technique used to create precise bends in thermoplastic materials such as acrylic (Perspex), polycarbonate, and PETG. It involves heating a narrow “line” across the plastic sheet using a heated element or filament until it becomes pliable. Once softened, the material is bent along that line and held in place until it cools and solidifies, maintaining its new shape.
Commonly used plastics for Line Wire Bending include acrylic (PMMA), polycarbonate, PETG, and other thermoformable plastics. These materials respond well to controlled heat, allowing for clean and accurate bends. Each material may react slightly differently to the process, so it’s important to select the most appropriate one based on the application.
Line Wire Bending is widely used to fabricate items such as display stands, point-of-sale (POS) units, leaflet holders, sign holders, equipment covers, machine guards, and bespoke retail displays. It is especially beneficial when consistent, sharp angles or multiple identical bends are required across batches of parts.
Line Wire Bending is a highly accurate process, especially when performed by experienced plastic fabricators using professional jigs and templates. This precision ensures consistent bend angles and repeatability for batch production. Accuracy depends on factors such as heat control, timing, material type, and bend design.
Compared to methods such as thermoforming or manual bending, Line Wire Bending offers several advantages:
- Precision – Straight, clean bends at exact angles.
- Efficiency – Ideal for batch runs or repeated bends.
- Speed – Faster setup and production times for certain products.
- Minimal distortion – Maintains optical clarity in transparent plastics like acrylic.
Yes, Line Wire Bending is well-suited to multi-bend plastic components, especially when using jigs to ensure consistency. Multiple lines can be bent in succession, allowing for the creation of complex shapes like U-frames, Z-shapes, and folded enclosures. However, extremely intricate designs may be better suited to CNC routing or thermoforming in combination.
Typically, plastic sheets ranging from 2mm to 10mm thick are ideal for Line Wire Bending. Thinner materials are easier to heat and bend but can be more prone to warping if not properly supported. Thicker sheets require longer heating times and may need additional support during cooling to maintain accuracy and structural integrity.
Yes, tight bend angles such as 90° folds are commonly achieved with Line Wire Bending. The process allows for sharp, well-defined corners, especially in acrylic and PETG. The achievable angle depends on material thickness and the heating duration, and precision can be improved using formers and bending jigs.
Absolutely. Line Wire Bending is a cost-effective and scalable solution for producing multiple identical parts. With the right tooling and setup, manufacturers like Dipec can produce large quantities of bent plastic components with consistency and minimal variation, making it an ideal process for commercial and industrial applications.
When done correctly, Line Wire Bending does not significantly compromise the strength or clarity of the plastic. For materials like acrylic, slight whitening can occur at the bend if overheated, but this can be minimised with expert handling. The key to preserving strength and aesthetics lies in precise heat control and skilled fabrication techniques.
