The Power of Sintering in Custom Manufacturing: A Comprehensive Guide

Sintering, a cornerstone of powder metallurgy, has revolutionized custom manufacturing by enabling the production of complex components with precise specifications. This time-tested process continues to evolve, offering manufacturers unprecedented capabilities in creating high-performance parts across various industries.

Understanding Sintering Technology

Sintering is a thermal treatment process that transforms powdered materials into solid masses without fully melting them. The process occurs at temperatures below the melting point of the primary constituent, typically between 60-70% of the melting temperature. During sintering, atomic diffusion drives the powder particles to join together, eliminating the intermediate void spaces and creating a dense, solid component.

The Sintering Process Steps

  1. Powder Preparation and Compaction
    • Selection of appropriate powder materials
    • Mixing of powders in precise ratios
    • Initial compaction to create the "green" body
    • Addition of binding agents when necessary
  2. Thermal Processing
    • Controlled heating to specific temperatures
    • Maintenance of optimal atmospheric conditions
    • Precise temperature profile management
    • Carefully controlled cooling rates
  3. Post-Processing
    • Dimensional verification
    • Surface finishing
    • Heat treatment (if required)
    • Quality control inspection

PartzPro Frequently Asked Questions

The "Open-Book" Business Model

Q: Why is there a factory invoice in the box?
That is your Commercial Import Invoice. Because we ship Factory Direct to your door, international customs requires an invoice that travels with the package.
  • Transparency & Compliance: This invoice lists the origin factory (showing you exactly who made your parts) and declares the exact value you paid at checkout.
  • Why it matches your payment: We ensure the commercial invoice matches your transaction value so that Customs calculates your duties correctly and legally, preventing delays or penalties at the border.
Q: Why don't you offer Instant Quotes?
May not be accurate: Some instant quotes are low instantly, then email you 24 hours later to raise the price once a human actually looks at it. We measure twice, cut once. We have the factory validate the CAM strategy before we give you a price. You wait a few hours, but the price you get is the price you pay—guaranteed. No surprises.
Q: If I have the factory’s info, why shouldn't I just go direct next time?
First, strictly speaking, you cannot. To protect our platform, our Terms of Use include a Non-Circumvention clause that prohibits direct transactions with our suppliers for 24 months.

But practically, clients stay for the "US Shield." When you order through PartzPro, your money is held in US-based Escrow. We handle the legal leverage, language barriers, and financial security. If you go direct, you lose that protection and have zero recourse if something goes wrong.
Q: What exactly does your Service Fee cover?
Your fee covers Financial Security (Escrow), Vendor Vetting, AI Engineering Analysis, and Project Management. We act as your US-based legal firewall. We find the best factories, negotiate the rates, and hold the money until the job is done right.

Logistics, Customs & AI Technology

Q: Who handles the HTS Codes and Customs paperwork?
Our AI does the heavy lifting; you just confirm the release. We don't leave you guessing on complex government tariffs.
  • Heavy AI Analysis: Our proprietary AI Assistant performs a 40-point analysis of your part's geometry and material. It automatically searches the official US Government HTS database to generate a precise HTS Code Breakdown for your specific parts.
  • The Process: This data is provided to the carrier (DHL/FedEx/UPS). When the broker contacts you, the classification is already estimated—you simply confirm it to release the shipment.
Q: Who pays the duties?
You do—which saves you money. Because we ship DAP (Delivered at Place), you pay the exact duties owed to the government based on the AI-generated HTS code.
  • Why this is better: Competitors who offer "Free Shipping/DDP" often inflate the price to cover the worst-case tariff scenario. By paying the actual duties yourself, you ensure you are never overcharged for import taxes.
Q: How fast is shipping?
Since we skip the "Middleman Warehouse," our standard international shipping is extremely fast (typically 3–5 days transit). Your parts fly directly from the machine shop to your desk.

Quality Assurance & Liability

Q: Competitors inspect parts at a US warehouse before shipping. Why don't you?
Because "double handling" kills speed and adds unnecessary cost. We operate on a "Dock-to-Stock" model. The factory performs the rigorous QC, and parts ship directly to you.

We treat you like a professional: we know you will verify the fit and function of your parts upon arrival. By removing the redundant middleman inspection, we save you on cost and 3–5 days on lead time.
Q: What happens if the parts arrive out of spec?
You are protected by the PartzPro Escrow Guarantee. Because we hold the funds, the factory does not get paid until you verify the order.

The Process: You have a 3-Day Inspection Window upon delivery to verify fit and function. If parts are non-conforming, simply upload a photo and inspection report within that window. We will either force an immediate priority remake at the factory’s expense or issue a refund.

*Bulk Order Extension: For large volume orders, this inspection window can be extended. To request an extension, simply reply to your automatic invoice email.
Q: Does your AI just check for geometry errors?
No. Our AI Cost-Driver Audit goes beyond simple DFM (Design for Manufacturing). It helps you perform Value Engineering by highlighting features that are disproportionately expensive (e.g., deep pockets, tight radii, non-standard threads). We show you the cost drivers so you can engineer the price down before you order.

Payments & Corporate Orders

Q: We are a company, not a hobbyist. Can we pay via Purchase Order (PO)?
Yes. We specialize in serving agile engineering departments and mid-sized manufacturing firms.
  • How to order with a PO: You can select "Pay via PO / Wire" at checkout or email our sales team directly with your PO attached. We will verify your company details and send a payment link or wire instructions immediately so production isn't delayed.
Q: Do you offer Net-30 Terms?
We offer terms to qualified business partners after an initial credit review. Please contact our sales team to set up your corporate account. For new customers, we recommend using our PO-to-Wire workflow for the fastest start.
