Stretching Processing

Stretching
Processing

The process of applying tensile and compressive loads to metal and other sheet materials (with a thickness of 0.2-8mm) through molds to make the blanks plastically flow and form open hollow parts; it covers single-step deep drawing, multi-step deep drawing (including multiple deep drawing and forward-backward deep drawing), and is suitable for mass production of large quantities of hollow parts such as cylindrical, box-shaped, and curved surface shapes.

Do you have any of the following problems
in the procurement of stretched components?

icon-troubles-1

Do you need to rework the deep drawing parts that have wrinkled or cracked?

Simulation predicts wrinkling (insufficient clamping force).
Risk of cracking (insufficient drawing ratio).
Optimize structural parameters in advance.
icon-troubles-2

It's difficult to control the dimensional accuracy?

Mold design incorporates springback compensation.
A shaping process is added after deep drawing.
This ensures dimensional consistency of the hollow parts.
icon-troubles-3

High cost and long production cycle of molds?

Reuse of standardized mold modules.
30% reduction in mold cycle time for complex parts.
Mold cost spread across large-volume orders.
icon-troubles-4

Does material selection affect the final product?

Shallow drawing: SPCC cold-rolled steel.
Deep drawing: DC04 deep-drawing steel.
(Yield strength ratio ≤ 0.7, elongation ≥ 40%).
icon-troubles-5

The delivery date has been delayed due to the complex process?

Mature process library matching.
Deep drawing + trimming + shaping compound die.
Single-process efficiency improvement of 50%+.

One-Stop Service For Deep Drawing (Stretching) Processing

From prototype design development, prototyping, large and small batch production, providing various materials and finishes,
we offer professional, fast and cost-effective solutions for your project

icon-searvice-1

Deep drawing
die design

Using AutoForm/Deform software to simulate material flow and stress distribution, we optimize the die clearance, blank holder force curve, and draw bead layout to prevent wrinkling and cracking.
icon-searvice-2

Preparation of the material
before deep drawing

CNC cutting of drawn sheets (accuracy ±0.5mm, matching the mold blank size), surface cleaning (to remove oil stains/oxide layers and prevent mold wear), and deep drawing lubrication.
icon-searvice-3

Single-action
pull processing

Suitable for shallow drawn parts (such as small boxes and short cylinders), formed by "single-stage deep drawing" using a single-acting hydraulic press, with simultaneous control of blank holder force and drawing force.
icon-searvice-4

Dual-action
pull processing

Suitable for deep drawing / complex curved parts, the double-action press features independent control of blank holding (outer slide) and drawing (inner slide), improving forming accuracy.
icon-searvice-5

Multi-station
continuous deep drawing

Suitable for high-precision small parts (such as connector housings), the multi-station mold continuously completes "deep drawing → punching → trimming → shaping," with a cycle time of up to 60 pieces per minute.
icon-searvice-6

Flanging and edge trimming
shaping processing after deep drawing

The deep-drawn parts undergo CNC trimming (to remove burrs from the edges) and hot forming (to correct stainless steel springback), ensuring assembly dimensional tolerances of ≤ ±0.1mm.
icon-searvice-7

Deep drawing part
heat treatmen surface treatment

Using a composite mold, multiple processes (punching + blanking + shallow drawing) can be completed in a single stamping operation, reducing the need for subsequent assembly.
icon-searvice-8

Deep drawing
component assembly

Precision riveting/welding of multiple deep-drawn parts (such as washing machine inner drum + end cap assembly), combined with sealing/fastening processes, to deliver finished components ready for direct installation.

Polyethylene (PE)

It has good temperature resistance, strong chemical stability, moderate cost, and its performance can be adjusted through modification. Its models are mainly classified according to "copolymer structure" and "application characteristics", and are suitable for stamping processes, mainly including blanking, shallow bending, and simple forming, but not suitable for complex deep stretching.
