Look for brands like Siemens or Mitsubishi for PLCs, Schneider or ABB for electrical systems, and Rexroth or Yuken for hydraulic pumps. This ensures reliability and easier spare parts sourcing globally.
Machine Performance and Specifications
Move beyond glossy brochures to hard data. Your technical inquiry should demand clarity on:
* Core Metrics: Production output (bricks per hour, shifts per day), pressing force (in tons), and cycle time (seconds per brick).
* Flexibilidade: What range of brick sizes (e.g., hollow blocks, solid blocks, pavers) can the standard machine produce? What is the process and cost for custom molds?
* Nível de Automação: Does it require 10 workers or 2? Match the automation level to your available labor and investment budget.
* Eficiência Operacional: Request data on energy consumption (kW per cycle) and noise levels. Efficient machines have a lower long-term operational cost.
After-Sales Service and Support
This is where partnerships are made or broken. Scrutinize their support structure:
* Garantia: A standard warranty is 12-18 months for the whole machine, with 1-2 years for the hydraulic system and mainframe. Read the terms—what is excluded?
* Suporte Técnico: Is support available in your time zone? Do they offer remote diagnostics? What is their target response time?
* Peças de Reposição: Guarantee the availability of spare parts for a minimum of 10 years. Ask about their parts supply chain and typical shipping times for your region.
* Commissioning & Training: Will they send an engineer for installation and commissioning? Is operator training provided at their factory or on your site? Clarify all associated costs.

Understanding Logistics, Shipping, and Customs
Plan for the journey from their factory floor to yours.
* Incoterms: Understand your responsibilities. FOB (Livre a Bordo) means you own the goods and handle costs/risks once they’re loaded on the ship in China. CIF (Custo, Seguro e Frete) means the supplier arranges and pays for shipping to your nearest port. FOB is generally recommended for greater control.
* Parceria com um Agente de Carga: A reliable forwarder handles complex logistics, customs clearance, and final inland delivery to your door.
Payment Terms and Contract Safeguards
Protect your investment with clear agreements.
* Standard Payment Terms: A common and balanced term is 30% deposit via T/T (bank transfer), 70% balance against copy of Bill of Lading. This shares the risk between buyer and seller.
* The Contract is Key: Ensure the final, signed Proforma Invoice (PI) or commercial contract includes all technical specifications, warranty details, delivery timeline, and agreed payment terms. This document is your legal safeguard.
Common Pitfalls to Avoid When Sourcing from China
Forewarned is forearmed. Steer clear of these frequent mistakes.
Choosing Based on Price Alone
The cheapest machine is often the most expensive in the long run.
* Custos Ocultos: Inferior steel, low-grade hydraulics, and poor machining lead to frequent breakdowns, high maintenance costs, excessive downtime, and a short machine lifespan. Calculate Custo Total de Propriedade, not just purchase price.
Overlooking After-Sales Service
A machine without support is a liability.
* Verify Support Networks: Does the manufacturer have a history of servicing machines in your region? Do they have local agents or partners? A supplier unwilling to discuss detailed service plans is a major red flag.
Vague Contracts and Specifications
Verbal promises have no value in international trade.
* Document Everything: If a feature, a specific component brand, or a performance metric was promised during negotiations, it must be written into the contract. Ambiguity favors the seller if disputes arise.
