How long is the sample lead time?webadmin2025-06-30T04:34:30+00:00

How long is the sample lead time?

The lead time for samples can vary depending on your specific project. Here’s a general idea:

Standard parts or existing molds:
If your part matches something we already produce, samples usually take about 3 to 7 days, depending on stock and shipping times.
Custom molded or machined parts:
For new designs that require custom molds or mechanical processing, it usually takes 2 to 5 weeks to produce samples. This period includes the time for mold fabrication, preparatory work, and making minor adjustments according to your requirements.
3D-printed prototypes:
If you need to obtain the prototype product quickly, we also offer 3D printing services in metal or plastic materials. These samples can usually be completed within 3 to 5 days, depending on factors such as size, material, and surface treatment requirements.
Special finishes or testing:
Surface treatments like anodizing, black oxidize, painting, etc.(click here to see our options), or specific functional tests might add a bit more time.

Once we know your part details, we’ll confirm the timeline and keep you posted throughout the process. Feel free to share your drawings or ideas so we can give you a more precise estimate!

Can I get samples for testing?webadmin2025-06-30T04:35:35+00:00

Can I get samples for testing?

Yes, absolutely. At KingStar, we understand how important it is to check the quality and fit of your parts before moving into mass production.

In most cases, we can provide samples in small quantities — usually between 1 and 10 pieces (for 3D printing, CNC machining), or 10 to 100 pieces (for injection molding) depending on your part’s size, complexity, and production method.

We offer several options for making samples:

3D Printing (Metal or Plastic): Great for fast prototypes or design validation, usually ready in just a few days. We usually provide 1-3 pcs as samples.
Trial Runs from Injection Molding: For plastic parts requiring high accuracy or specific materials, we can run small batches (usually 10-100 pcs) using soft or production tooling.
CNC Machining: Ideal for metal or plastic parts needing precise tolerances or certain material properties before committing to tooling. For machining, we usually provide 1-5 pcs as samples.

However, this is not fixed. If you need more samples than we usually provide, we are open to negotiate, and if your project requires special finishes, surface treatments, or functional testing, we’re happy to include those in the sampling process as well.

Let us know your part details, and we’ll advise the best way to produce your samples quickly and cost-effectively.

How do I choose the right CNC machining service for my project?webadmin2025-07-15T03:13:08+00:00

How do I choose the right CNC machining service for my project?

Choosing the right CNC machining partner isn’t just about checking boxes—it’s about finding a team that understands your project’s unique kinks and can navigate them. Here’s how to sift through the options:

Start with their shop floor: Do they have the right tools for your part’s geometry? A part with tight internal angles might need 5-axis machines to reach those spots, while a simple flat component could work with 3-axis milling. Ask to see examples of similar parts they’ve made—if they’ve tackled something with your design’s quirks, that’s a good sign.

Next, drill into material know-how. Aluminum’s tricky for thin walls—does their team know how to adjust feed rates to prevent warping? For plastics like PEEK, have they dealt with its high melting point and how it clings to tools? Experience with your material means fewer surprises, like unexpected cracks or surface blemishes.

Precision matters, but not all tolerances are equal. If your part needs to slot into a precision assembly with ±0.001mm tolerance, ask how often they calibrate their CMMs. A shop that checks tools daily is less likely to miss the mark than one that does it monthly. For looser tolerances (say, ±0.05mm), focus on consistency across batches—no one wants half a run that fits and half that doesn’t.

Timelines are another puzzle. Rapid prototypes might need to ship in 3 days, but production runs with custom tooling could take 4 weeks. The best partners will be upfront about bottlenecks—like material lead times for rare alloys—and adjust timelines accordingly. Beware of promises that sound too fast; rushing often means cutting corners.

Costs add up in hidden ways. A prototype might cost more per unit, but as volumes hit 10,000, ask if they can optimize toolpaths to cut material waste—saving you 10-15% on bulk runs. Watch for hidden fees, too: some shops charge extra for post-machining deburring, others include it. Transparency here builds trust.

Lastly, test their responsiveness. If you tweak a design mid-project, do they get back with revised timelines in a day, or leave you waiting? A partner that walks through DFM tweaks—like suggesting a rounded corner to avoid tool breakage—shows they’re invested in your part’s success, not just their bottom line.

At KingStar Mold, we start by understanding your project’s pain points—whether it’s that tight tolerance or a finicky material—and build a process around solving them. No two parts are the same, and neither should be the approach.

What is the difference between CNC milling and CNC turning?webadmin2025-07-15T03:20:48+00:00

What is the difference between CNC milling and CNC turning?

At their core, CNC milling and CNC turning part ways in how they interact with material—starting with the very movement that shapes the part.

CNC milling relies on a spinning tool: imagine a multi-fluted end mill or drill bit whirring at high speed. It’s the tool that does the “moving” here, shifting along X, Y, and Z axes (or more, for complex setups) while the workpiece stays steady. This flexibility lets it carve out parts with irregular shapes—think a bracket with angled edges, a panel with off-center holes, or a component with grooves that twist. The tool dives, shifts, and rotates to match the part’s unique contours, making it the pick for pieces where symmetry takes a backseat to detail.

CNC turning, by contrast, puts the workpiece in motion. Clamped in a rotating chuck, the part spins rapidly while a stationary (or slowly moving) single-point tool meets it. This rotation centers the cutting action, so it excels at rounded, symmetrical parts: a shaft that needs consistent diameter from end to end, a bolt with evenly spaced threads, or a cylindrical sleeve that must fit snuggly into a circular housing. The tool skims across the spinning surface, shaving away material to create smooth, uniform curves—no jagged edges, just precision in every rotation.

The split grows clearer in practice. Milling handles the “oddballs”: parts with non-circular profiles or features that jut out at angles. Turning masters the “regulars”: pieces where every point on the edge needs to line up perfectly around a central axis. And often, they team up—say, a turned rod that later gets a flat, milled slot to lock into another component. Each plays to its motion, turning raw material into something tailored to its purpose.

Is CNC machining suitable for complex geometries?webadmin2025-07-15T04:37:10+00:00

Is CNC machining suitable for complex geometries?

CNC machining isn’t just up to handling complex geometries—it’s often the best way to make them. The trick lies in how modern setups adapt to tricky shapes, whether it’s a part with curves, angles, or nested features that would baffle simpler tools.

Take multi-axis machines, for example. A 5-axis CNC mill doesn’t just move up, down, left, right, and forward—its spindle can swivel and rotate, letting the cutting tool reach around the workpiece like a sculptor’s hand. Need a turbine blade with a twisted, curved surface that tapers at both ends? The machine tilts and turns, keeping the tool aligned with every contour so cuts stay precise, no matter how the shape bends.

Then there’s the software that drives it. CAD/CAM programs take a 3D model—say, a medical instrument with tiny, off-center holes and a grooved channel winding through it—and break it down into step-by-step toolpaths. The machine follows these paths exactly, even for parts with “hidden” features, like an undercut inside a cavity that a regular 3-axis mill couldn’t reach without crashing the tool.

Tooling helps too. Small, rigid end mills with sharp, multi-fluted tips can carve fine details: think of a robotics part with thin walls (only a millimeter thick) that curve gently, or a sensor housing with a maze of tiny slots. These tools cut smoothly, avoiding the jagged edges that would come from trying to shape such parts by hand.

Of course, there are limits. A part with a slot narrower than a hair, or a curve that bends back on itself in a way no tool can reach, might need extra steps—like electrical discharge machining (EDM) for the tiniest features. But for most complex shapes—from aerospace brackets with compound angles to custom enclosures with asymmetric cutouts—CNC machining handles them reliably, batch after batch.

It’s not just about making the shape—it’s about making it consistently. Even the most intricate design comes out the same every time, which is why industries like automotive and aerospace rely on CNC for their trickiest parts. When geometry gets complicated, CNC machines don’t just keep up—they excel.

What materials can be CNC machined?webadmin2025-07-15T05:31:29+00:00

What materials can be CNC machined?

CNC machining can handle various materials, but its effectiveness depends on the material’s ability to maintain its shape under the action of cutting force.

Metals such as aluminum 6061 and 316 stainless steel are commonly used materials – the balance of aluminum’s strength and machinability makes it suitable for a wide range of products from brackets to housings, while the corrosion resistance of stainless steel is suitable for components in harsh environments. We have found that brass with good cutting performance performs exceptionally well in electrical components, but we always prepare new tools to avoid damaging its soft surface.

Plastics have their place too. ABS is reliable for prototypes, nylon works for low-friction parts like gears, and PEEK stands up to high heat—we once machined PEEK valve components for industrial ovens, using slow feeds to prevent melting. Composites like carbon fiber-reinforced plastics need diamond tools to handle their abrasive fibers, a trick we picked up from making drone frames that demand both lightness and strength.

Not every material fits, though. Super-soft materials like lead or indium tend to gum up tools and deform under cutting, making precision impossible. Extremely brittle materials—some ceramics, for example—shatter easily under the tool’s pressure. And highly elastic materials like unmodified rubber? They stretch instead of cutting cleanly, leaving ragged edges that won’t hold tolerances. For these, other methods like casting or molding usually work better.

In the end, CNC thrives where materials hold their form under controlled cutting. With the right approach, it turns most metals, plastics, and composites into precise parts.
