Na Luoyang Fonyo Heavy Industries Co., Ltda., garantir a mais alta qualidade de cada componente é nossa principal prioridade. Nosso abrangente inspeção de qualidade de fundição e usinagem procedimentos garantem precisão, durabilidade, e desempenho paraR peças metálicas personalizadas, incluindo componentes ferroviários, peças fundidas, e rodas. Da matéria-prima à entrega final, empregamos métodos avançados de inspeção e teste para atender aos padrões da indústria e aos requisitos do cliente.

Inspeção de qualidade de material recebido

Antes mesmo de iniciarmos a produção, garantimos que as matérias-primas estão à altura da tarefa. Material de baixa qualidade causará problemas, não importa quão bom seja o processo, então verificamos cuidadosamente:

Composição Química: Executamos testes de espectrômetro para garantir que o metal é exatamente o que o desenho exige.
Propriedades Mecânicas: Resistência à tracção, dureza, e os testes de impacto nos dizem se o material pode suportar o estresse do mundo real.
Verificação de Fornecedor: Certificados e documentos de rastreabilidade são revisados – queremos saber a origem de cada lote.

Getting materials right from the start saves headaches later.

Casting Process Quality Control

Casting can be tricky, especially for high-load parts like wheels or housings. Ao longo dos anos, we’ve developed a set of checks that catch the problems before they leave our shop:

Stage	Method	Propósito	Typical Parts
Superfície & Dimensões	Visual check, calipers, micrômetros, CMM	Make sure there are no cracks, porosidade, and dimensions are correct	Rodas, alojamentos, peças fundidas
Internal Defects	PT (penetrant), EUA (ultrassônico), RT/X-ray, MT (partícula magnética)	Find surface and internal defects you can’t see	Fundições, thick components
Mecânico	Dureza, impact/Charpy test	Confirm strength and toughness	Rodas, structural parts
Microestrutura	Análise metalográfica	Check grain structure and phase distribution	Critical castings
Tratamento térmico	Hardness and microstructure	Ensure proper mechanical properties	Fundições, rodas

These aren’t just steps on a checklist—they’re methods we’ve learned are most effective in catching real-world problems before parts go out the door.

Machining Process Quality Inspection & Teste

Once the casting is done, machining is where precision matters most. Our philosophy: measure as you go, and don’t assume anything.

Stage	Method	Why We Do It
Precisão Dimensional	CMM, micrômetros, gauges	To make sure holes, eixos, and mating surfaces match the drawing perfectly
Acabamento de superfície	Medição de rugosidade	Smooth surfaces reduce friction and wear in operation
Functional Fit	Assembly checks, test fitting	Ensures parts work together without adjustment
In-Process Monitoring	Continuous observation	Catch deviations immediately rather than waiting until the end

By checking continuously, we can catch small errors early and keep all parts within tight tolerances.

Non-Destructive Testing and Mechanical Verification

Experience has shown us that combining multiple methods works best. Here’s a quick overview:

Method	What It Checks	When We Use It
PT (Penetrant)	Rachaduras superficiais	During casting inspection
EUA (Ultrassônico)	Internal defects	During casting inspection
RT/X-ray	Internal porosity, inclusões	Critical castings
MT (Magnetic Particle)	Rachaduras superficiais	Ferromagnetic components
Hardness Test	Material strength	Após tratamento térmico
Impact Test	Resistência	For parts that need to absorb shocks
Metallography	Microestrutura	Confirm proper grain and phase distribution

Layering these methods helps us feel confident that the parts will perform under real-world conditions.

Final Product Verification of Quality Inspection

Antes do envio, we do a last set of checks—more than just numbers:

Verificação Dimensional: Every critical dimension is checked to make sure tolerances are met.
Functional Testing: Simulated operation ensures the part performs as intended.
Embalagem: Careful packing prevents damage during shipping.

We want every part—whether a railway wheel, fundição, or machined component—to arrive ready to work without surprises.

Why Choose Us for Casting and Machining Quality

From our perspective, quality isn’t just a department—it’s a mindset:

Industry Expertise: Our inspection processes are tailored for rail, automotivo, energia, and heavy machinery applications.
Advanced Equipment & Skilled Engineers: CMM, NDT tools, and hands-on experience make our checks reliable.
Soluções personalizadas: We work directly from your drawings or samples to produce exactly what you need.
Confiabilidade & Segurança: Every test and measurement is done as if we were going to use the part ourselves.

We approach each project like we would for our own machines—carefully, deliberately, and with real-world experience behind every decision.
