TOOLING DIE SETS

Tooling Die Sets

What Is a Die Set?

A die set is the rigid frame of a stamping tool. It carries the upper and lower die halves on a pair of plates, keeps them aligned with guide posts and bushings, and sets the shut height with spacers. This structure holds every punch, die and forming part in position through each press stroke.

✓Built to your drawing

✓MISUMI / HASCO / DME compatible

✓Precision guide alignment

Die Set Components

What a Die Set Contains

Most die sets are built from the same core components, arranged around your tool layout.

Schematic section — numbers match the list.

Upper & Lower Plates
Carry the die components and mount to the press.

Guide Post & Bushing
Keep the upper and lower halves aligned stroke after stroke.

Spacer & Support Blocks
Set shut height and support the plates against press load.

Clamping Plates
Hold punch and die retainers firmly in the plate stack.

Die Set Materials & Tolerances

Values below are typical reference ranges. Final material, tolerance and hardness follow the drawing and application requirements.

Component	Material Options	Tolerance	Hardness
Upper & Lower Plates	Tool steel / Mild steel / 45# (medium carbon steel)	±0.01–0.02 mm	30–45 HRC
Guide Post & Bushing	SKD11 / SKH-9 / SUJ2	±0.005 mm	58–62 HRC
Spacer & Support Blocks	Pre-hardened steel / Mild steel	±0.01 mm	28–35 HRC
Clamping Plates	Tool steel / Customized	±0.02 mm	30–45 HRC
Non-standard Bases	As per drawing	As requested	As required

Standard Base or Custom Mould Set?

Most projects fall into one of two paths.

Standard Die Sets

Fits common sizes and regular layouts

Typically for high-volume progressive dies with known plate sizes and standard mounting.

Main points

✓Pre-configured plate sizes and post positions

✓MISUMI / HASCO / DME reference

✓Tolerance ±0.01–0.02 mm typical

To confirm

Overall plate size and shut height

Start here if your press and plate sizes follow common standards.

Custom Mould Bases

Fits special layouts and non-standard needs

For special equipment, prototypes and configurations that do not follow a standard base.

Main points

✓Built to your drawing and plate layout

✓Material, size and layout per requirement

✓Tolerance as per drawing

To confirm

Drawing with plate layout and guide positions

Start here if the layout is special or the part is still in prototype.

Standard and custom die sets across automotive, electronics, home appliances and consumer hardware.

What to Confirm Before Ordering

These details help us confirm whether a standard base fits or a custom set is needed.

□ Overall plate length and width

□ Shut height / spacer thickness

□ Press mounting hole pattern

□ Guide post position and type

□ Plate material requirement

□ Standard compatibility (MISUMI/HASCO/DME)

□ Any special opening or cutout

□ Quantity and delivery target

A drawing, plate sizes and the press model are enough for a first review — share what you have.

Machining & Inspection for Die Sets

Machining capability

Plates, guide components and spacers are machined in-house.

Process	Equipment & Brand	Capacity	Accuracy
Plate Milling & Drilling	AWEA · AGMA · Vision Wild (Taiwan)	Up to 1600 × 3100 mm	±0.005–0.01 mm
Plate Surface Grinding	Okamoto · Chevalier (large surface grinders)	600 × 1200 mm	±0.001 mm · Ra0.02
Conventional CNC	DTX850 · VLB-121	Up to 750 × 1300 mm	±0.01 mm

Capacity = maximum workpiece size; accuracy = machining tolerance.

Inspection

Flatness, parallelism and hole positions are verified before shipment.

Tooling Die Sets — Common Questions

What tolerances and materials are available for die set plates?+

Plates are machined to ±0.01–0.02 mm with hardness from 30–45 HRC, in tool steel, mild steel or 45#. Guide posts and bushings hold ±0.005 mm at 58–62 HRC. Non-standard bases follow your drawing.

What is the difference between a die set and a stamping die?+

A die set is the structural frame — the plates, guide posts, spacers and clamping plates that carry the die halves and keep them aligned. The stamping die itself is the tool that cuts, forms or pierces the part. Die sets form the foundation that lets the die work accurately stroke after stroke.

How do I choose between a standard die set and a custom mould base?+

Standard die sets follow standardized sizes and layouts for high-volume production. Custom mould bases are built to your drawing for unique design or dimensional requirements. Send the plate sizes and press model, and we will recommend the path that fits.
