Rapid Prototyping Services

You should never cut steel for a mold before you have held the part in your hand. We offer three prototype routes — 3D printing, CNC from billet and soft tooling — so you can pick the one that matches your deadline and budget.

ISO 9001-aligned quality system

Samples as fast as 10–15 days

Expert DFM & engineering support

100% dimensional inspection

Why Prototype Before Tooling?

A production mold is a five-figure commitment and a four-to-six week lead time. If the design changes after it is cut, you pay for both the change and the delay.

A prototype answers the questions that a 3D model cannot: does it fit the mating part, does it survive the drop test, does the wall thickness actually fill, does the finish look right in the hand.

We use prototype results as design input — adjusting gate position, cooling layout and ejector placement before the production mold is cut. That is where the real saving is.

Die Casting Production Process

Four stages, each with a check you can audit.

01 Design Review

We check the model for draft, wall thickness, gate position and ejector placement, and flag what will be expensive to cast.

02 Route Selection

3D printing for form and fit, CNC from billet for real material properties, soft tooling when the design is nearly final.

03 Prototype Build

3–7 days for printed parts, 5–12 days for machined parts, 15–25 days for a prototype mold.

04 Validation & Handoff

You test the part. We fold the findings into the production mold design before cutting steel.

One-Stop Die Casting Solution

Five capabilities under one production plan. Most projects use three or four of them.

Die Casting Prototyping

Validate fit and function before tooling is cut.

Die Casting Tooling

In-house mold design and build, 1–4 cavities.

Aluminum Die Casting

HPDC from 160T to 1,250T for structural parts.

Secondary CNC Machining

Tapped holes, sealing faces, ±0.02 mm.

Surface Finishing

Coating, painting, anodizing, plating.

Why Choose SUNGREAT

What separates a casting supplier from a manufacturing partner is what happens before the mould is cut and after the parts are packed.

Three routes, one supplier

Print, machine or soft-tool without shopping around for different vendors.

Real material properties

CNC prototypes are cut from the same alloy you will cast, so strength tests mean something.

Fast turnaround

Printed parts in as little as 2–3 days; machined parts inside two weeks.

Feeds the mold design

Prototype findings directly change gate and cooling layout.

Applications

Where this capability is usually specified.

Form and fit checks

Client and investor presentations

Drop and strength testing

Thermal validation

Assembly trials

Low-volume bridge production
