Plastics used in molding are available in a wide range of grades (e.g., ABS, Polypropylene, Polycarbonate), each with distinct mechanical, thermal, and chemical characteristics. The grade determines the part’s durability, flexibility, and regulatory compliance (e.g., food-safe, flame-retardant). Accurately specifying material grade is essential for ensuring that finished products meet the mechanical and safety requirements of your target market, whether for automotive components in Germany or consumer goods in Nigeria.

2. Dimensional Tolerance
Tolerance specifies the acceptable variation in the molded part’s dimensions. Typical tolerances range from ±0.01 mm for high-precision parts to ±0.1 mm for general goods. Inconsistent tolerances can cause assembly issues, functional failures, or increased post-processing costs. Specifying and verifying tolerances helps maintain consistent quality, especially critical for sectors like medical, electronics, or automotive supply chains.

3. Surface Finish
The surface finish refers to the texture and appearance of molded parts, often expressed as Ra (roughness average) values or with trade standards (e.g., SPI-A2, VDI 3400). Smooth finishes may be imperative for optical parts, while textured surfaces are common in consumer products. Surface finish can affect aesthetics, functionality (like seal properties), and further processing steps, so clear communication with suppliers is vital.

4. Machine Tonnage/Clamping Force
Clamping force, generally measured in tons, reflects the strength a molding machine uses to keep the mold closed during injection. The required tonnage depends on part size, geometry, and plastic type. Incorrect tonnage can lead to defects such as flash or incomplete filling. Suppliers with a wide range of machine tonnages offer more flexibility and reliability, particularly when you have diverse product lines.

5. Shot Size and Cycle Time
Shot size is the volume of plastic a machine can inject per cycle, impacting the maximum part size it can produce. Cycle time—the duration required to complete one molding cycle—directly affects production rates and lead times. Shorter cycle times support high-volume, cost-sensitive projects, while larger shot sizes are crucial for big or complex parts. Both are key metrics in supplier assessments, especially when scaling up operations.

6. Certification Compliance
Industry certifications (such as ISO 9001, IATF 16949, or ISO 13485) demonstrate a supplier’s adherence to recognized quality management systems. For regulated sectors (medical, automotive, electronics), specific compliance is often a prerequisite for market entry and long-term business relationships.

Common Trade Terms and Industry Jargon

Understanding essential trade terminology streamlines communications and negotiations between international partners. Here are frequently encountered terms in the machine plastic molding sector:

1. OEM (Original Equipment Manufacturer)
An OEM refers to a company that produces parts or products that are purchased by another business and retailed under that purchasing company’s brand name. In plastic molding, OEMs specify unique designs, often requiring tailored molding solutions and stricter confidentiality controls.

2. RFQ (Request for Quotation)
An RFQ is a formal document sent to potential suppliers outlining detailed specifications—drawings, volumes, quality requirements—for the part or assembly to be molded. A clear RFQ is crucial for obtaining accurate pricing, lead times, and assessing supplier capabilities, especially when dealing with multiple international bids.

3. MOQ (Minimum Order Quantity)
MOQ is the lowest quantity of units a manufacturer is willing to produce per order. Understanding MOQs is vital for cost calculations and inventory planning, particularly for businesses launching new products or those operating in markets with highly variable demand.

4. Incoterms (International Commercial Terms)
Developed by the International Chamber of Commerce, Incoterms define the responsibilities of buyers and sellers regarding shipping, insurance, duties, and risk transfer. Common Incoterms such as FOB (Free on Board), CIF (Cost, Insurance, and Freight), or DDP (Delivered Duty Paid) can significantly impact overall landed costs and logistic arrangements.

5. Lead Time
