Putter head manufacturers

B2B buyers should prioritize 303 Stainless Steel for a premium, soft feel and excellent corrosion resistance, or Carbon Steel for players who prefer a traditional 'muted' feedback. For high-MOI (Moment of Inertia) designs, look for Multi-material construction combining lightweight 6061 Aluminum bodies with heavy Tungsten weights to increase stability on off-center hits.

CNC Milling is the gold standard for precision, ensuring perfectly flat faces and consistent loft/lie angles, though it carries a higher unit cost. Investment Casting is more economically feasible for high-volume orders, but often requires secondary face milling to meet professional performance standards. Ensure the supplier uses 5-axis CNC machines for complex geometric designs.

When sourcing for a private label, confirm the Hosel Type (Plumber’s Neck, Slant Neck, or Center Shafted) as this dictates the 'toe hang' and suits different stroke types. Specify Face Groove Technology (such as C-Grooves or variable depth grooves) which are essential for reducing skidding and promoting immediate forward roll of the golf ball.

Products must adhere to the USGA (United States Golf Association) and R&A Rules of Golf, specifically regarding 'Appendix II' which governs clubhead dimensions, plain shapes, and neck configurations. Ensure the supplier provides CMM (Coordinate Measuring Machine) reports to verify that loft, lie, and weight tolerances are within +/- 1 degree and +/- 2 grams respectively.

Request a Pre-Production Sample (PPS) and subject it to a salt spray test to check finish durability (especially for PVD or Black Oxide finishes). Utilize Third-party inspection services to conduct 'During Production Checks' (DUPRO) to ensure the weight consistency across a batch, as weight variance is the most common defect in mass-produced clubheads.

Negotiate based on Total Landed Cost, but also push for Tooling Ownership clauses. If you pay for the molds/dies, ensure the contract stipulates that the intellectual property and physical molds belong to you and cannot be used for other clients. For long-term partnerships, aim for a tiered pricing structure where the unit price drops as your cumulative annual volume increases.

Putter heads are susceptible to 'chatter' (dents) during transit. Insist on individual bubble wrapping or custom foam inserts rather than bulk packing in a single bag. For shipping to the US or Europe, ensure the Harmonized System (HS) Code 9506.39 is used correctly to avoid customs delays and ensure accurate duty application.

Prioritize Audited Suppliers who have undergone on-site inspections by independent bodies like SGS or TÜV Rheinland. Use Secured Trading Services offered by the platform to ensure that payment is only released to the supplier after you have confirmed the Bill of Lading (B/L) or inspection report, protecting your capital against non-delivery or sub-standard goods.
