The End-to-End Quality Journey

• Step

  Contract Review & DFM

  Quality begins before the first cut.

  We do not rush into production. Upon receiving your order, our cross-functional engineering team (Project, Design, and Manufacturing) conducts a strict Design for Manufacturability (DFM) and compliance review.

  The Benefit:

  By proactively identifying tolerance conflicts and structural risks during the blueprint phase, we eliminate unnecessary tooling modifications and keep your project strictly on schedule.

• Step

  Prototyping & APQP

  Proving the concept with automotive-grade rigor.

  We execute Advanced Product Quality Planning (APQP) during the prototyping phase. By establishing comprehensive Control Plans and First Article Inspection (FAI) standards early on, we lock in the critical parameters required for success.

  The Benefit:

  “Sample approved” means “mass production approved.” We guarantee a seamless transition from prototype to high-volume manufacturing without unexpected quality drops.

• Step

  Source Material Gatekeeping (IQC)

  Garbage in, garbage out? Not on our watch.

  Every batch of raw material undergoes 100% compliance verification. We utilize advanced spectrometers for RoHS/composition analysis and precise hardness testers to validate material integrity. Every roll of steel and bag of resin is assigned a unique tracking lot for full traceability.

  The Benefit:

  You will never face an assembly-line disaster or a product recall caused by inferior, out-of-spec, or counterfeit raw materials.

• Step

  In-Process Quality Control (IPQC)

  Monitoring precision, minute by minute.

  This is where discipline meets technology. Our IPQC inspectors conduct strict routine patrols on the shop floor, backed by automated online monitoring, Coordinate Measuring Machines (CMM), and 2D vision systems. We utilize Statistical Process Control (SPC) data to track trends, and our team holds the authority to instantly halt production if a deviation is detected.

  The Benefit:

  Whether we are stamping Automotive EMI RFI Shields or executing wide-ranging overmolding services, you receive parts with stable CPK values and near-perfect yield rates, ensuring zero delivery delays.

• Step

  Outgoing Quality Control (OQC)

  The final firewall before global shipping.

  Before any component leaves our facility, it must pass a rigorous final release inspection based on strict AQL sampling standards. We also evaluate and apply customized packaging and protection protocols tailored to the demands of international freight.

  The Benefit:

  Ready for assembly the moment you open the box. Parts shipped across the globe arrive at your facility in the exact flawless condition they left our production line.

• Step

  Closed-Loop CAPA

  We don’t hide from issues; we engineer them out.

  In the rare event of an anomaly, our response is immediate and systematic. We deploy 8D reporting standards and Corrective and Preventive Action (CAPA) mechanisms to dig into the root cause rather than just treating the symptom.

  The Benefit:

  You get rapid, transparent resolutions. More importantly, our system learns from every challenge, ensuring the exact same quality deviation never happens twice.

Verified Input. Uncompromised Output.

Zero Compromise at the Source: Certified Material Sourcing & Strict IQC

We don’t just manufacture; we gatekeep your quality. By eliminating material risks before production begins, we radically reduce your trial-and-error costs and prevent assembly-line disasters.

Flexible Sourcing Strategies

We recognize that every supply chain is unique. Whether you require a fully managed material solution or prefer to supply your own, our infrastructure seamlessly adapts without ever lowering the quality barrier.

Turnkey Sourcing: Leverage our extensive, established network of compliant suppliers—each strictly audited against IATF 16949 and GJB 9001C standards. We take full responsibility for sourcing the exact metal strips and engineering plastics that match your precise project requirements. You define the specs; we secure the optimal materials.

Consigned Materials: Do you have a mandated global supplier for your raw materials? No problem. We seamlessly integrate your designated materials into our rigorous Incoming Quality Control (IQC) protocols and climate-controlled warehousing systems, ensuring they enter the production line in peak condition.

The IQC Firewall: Metal & Plastic

A fraction of a millimeter or a slight variation in moisture can trigger catastrophic failure in mass production. Our IQC lab acts as an uncompromising firewall against inferior inputs.

For Precision Stamping Metals: The Checkpoints: We enforce strict verifications for thickness tolerances, Hardness Testing, tensile strength, and RoHS/composition compliance utilizing advanced spectrometers. The Value: We guarantee that every EMI shield or contact pin stamped from our steel coils delivers absolutely consistent springback force, structural integrity, and long-term fatigue resistance.

For Advanced Engineering Plastics: The Checkpoints: Every batch of raw plastic pellets undergoes rigorous Moisture Analysis, Melt Flow Index (MFI) verifications, and shrinkage rate evaluations prior to entering the injection machines. The Value: We systematically eliminate the root causes of fatal molding defects—such as short shots, flash, voids, or dimensional warping—caused by moisture contamination or inter-batch resin variations.

100% Traceability Mechanism

Complete Transparency from Raw Material to Final Assembly

The Infrastructure: From the moment materials hit our receiving dock, our warehouse and IQC teams assign a unique Lot Number/QR Code to every single batch. This digital tag is permanently and inextricably linked to its original Material Certifications and Mill Test Reports.

Your Reassurance: Should any question arise during your product's lifecycle—even years down the line—it takes us only seconds to trace the exact component back to the specific day it was manufactured, the exact machine used, and the specific roll of steel or bag of resin it originated from. This is the ultimate peace of mind for high-end procurement.

Manufacturability Secured Before Tooling.

Cross-Functional DFM & Feasibility Review (The "Careful Yes")

We do not operate as a blind “print-to-part” vendor; we act as your engineering partner. We take the word “Yes” very seriously.

Before accepting any new project, our project managers convene a multidisciplinary team—including engineering, tooling, quality control, and manufacturing—to conduct a rigorous Design for Manufacturability (DFM) and manufacturing feasibility analysis.

Advanced Injection Molding

Our Hardcore Engineering Evaluation Includes:

For Precision Metal Stamping: Evaluating material yield strength, flat pattern interference, and springback margins.

For Advanced Injection Molding: Executing Moldflow analysis, optimizing gate locations, and proactively identifying shrinkage rates and draft angle requirements.

The Benefit to You: By identifying tolerance conflicts, structural flaws, and special characteristics early in the blueprint phase, we save you exorbitant mold modification costs and weeks of wasted trial-and-error time.

Precision Metal Stamping

Audit-Ready Before Mass Production.

Automotive-Grade APQP & Risk Mitigation

We apply the automotive industry’s highest error-proofing standards to every project you entrust to us. From small-batch prototyping to high-volume manufacturing, our cross-functional APQP team utilizes a proven, standardized pathway to ensure “sample approved” truly means “mass production approved”.

We do not just predict potential process failures; we embed preventive controls and error-proofing (Poka-Yoke) mechanisms directly into the process design, formulating strict Control Plans for both trial and mass production phases.

We let the data speak. Our quality team performs Measurement Systems Analysis (MSA) on critical instruments and conducts initial process capability studies during the pilot run, ensuring a process capability index of CPK≥1.33 before greenlighting mass production

To guarantee parts survive transcontinental shipping, we conduct drop tests and simulated transit evaluations prior to full-scale production.

PPAP Readiness: The Ultimate Green Light

Before shifting to full-speed production, we provide an airtight “passport” for your components.

Led by our Project Engineering Department, we deliver comprehensive Production Part Approval Process (PPAP) packages tailored to your specific submission level requirements. This complete compliance archive includes:

First Article Inspection (FAI) reports. Complete Material Certifications and Third-party testing reports.Process Capability (CPK/PPK) Data.Part Submission Warrant (PSW).

The Benefit to You: We deliver more than just perfect precision parts; we deliver complete, audit-ready compliance archives that give your Supplier Quality Engineers (SQE) absolute peace of mind.

Vigilant Line Discipline. Zero Escapes.

Zero-Defect Manufacturing & In-Process Control

Manufacturing Quality, Not Just Inspecting It.

We prove our quality not through luck, but through unforgiving error-proofing mechanisms, high-frequency equipment patrols, and scientific human management. Here is how we ensure zero-defect mass production on the shop floor.

Production Setup & Anti-Mixing Protocols

Quality loss often occurs in the exact moment a production line transitions between batches. At Kravzik, we enforce strict shop-floor discipline to ensure a 0% risk of cross-contamination.

Strict Line Clearance (The Veto Power): Before a new product run can begin, our IPQC team must formally approve the line clearance. 100% of the previous batch’s conforming products, rejects, scrap, and blueprints must be completely removed from the workstation to absolutely eliminate mixing risks.

Dedicated Equipment for EV Parts: For high-demand New Energy Vehicle components, we enforce a “fixed-machine production” rule. We never arbitrarily swap equipment, guaranteeing absolute stability in your critical processing parameters.

Dynamic First Article Inspection (FAI): FAI is not just a one-time morning routine. We mandate a completely new FAI—which must be sealed and hung at the machine—after any material change, mold maintenance, or even a standard machine halt exceeding 4 hours, as well as power or water outages. Without a passed FAI, the production line will not start.

Dual-Perspective IPQC & Layered Process Audits

We do not believe in sorting out bad parts at the end of the line; we believe in catching deviations the second they occur.

2-Hour High-Frequency Patrols: Our IPQC inspectors sweep the floor every two hours, verifying machine parameters, product performance, and operator compliance, logging all data directly into the Process Patrol Report. If consecutive defects are found, a strict 24-hour halt-and-correct mechanism is instantly triggered.

Poka-Yoke & 100% Gauging: We leave no room for guesswork. For components with threaded inserts, we execute 100% Go/No-Go gauge screening. For printed or engraved products, we mandate the use of custom error-proofing (Poka-Yoke) fixtures to eliminate misprints entirely.

Poka-Yoke & 100% Gauging: We leave no room for guesswork. For components with threaded inserts, we execute 100% Go/No-Go gauge screening. For printed or engraved products, we mandate the use of custom error-proofing (Poka-Yoke) fixtures to eliminate misprints entirely.

The Final Firewall & Human-Centric FQC

Before your components receive our “PASS” label and are shipped across the globe, they undergo an uncompromising final release procedure that balances strict standards with scientific management.

Human-Centric 100% Inspection: Machines experience wear, but humans experience fatigue. When performing 100% visual inspections on highly reflective or miniature parts (such as silver-plated items), we mandate a strict 10-minute rest for our FQC inspectors every 2 hours to relieve visual fatigue. This seemingly small, ESG-friendly detail is our strongest weapon in drastically reducing escape rates.

Customized Protective Packaging: To survive harsh transoceanic shipping, easily oxidized electroplated components (such as tin or silver-plated parts) are mandated by our OQC to be vacuum-sealed and stored in light-blocking packaging. Your parts arrive exactly as shiny and perfect as when they left the line.

In-House Reliability Lab Testing: As a final layer of reassurance, our independent laboratory validates batch integrity through rigorous testing. Based on your requirements, we perform hardness testing for metals, film thickness testing for plating, and salt spray testing for stainless steel components.
