Sectors We Serve

Precision metal parts for the products your customers already build

SINTS supports OEM buyers across lock hardware, medical devices, power tools, appliances, consumer electronics, structural PM parts, and custom specialty products.

Each sector begins with the part function and sourcing concern first, then connects the project to material, finish, process route, inspection, and volume production support.

Industry Application Areas

Buyers usually evaluate suppliers by application fit: whether the parts, surfaces, strength requirements, and production expectations feel familiar enough for a reliable first review.

Security Products

Lock Hardware and Access Control

Smart-lock internals, latch parts, lock cores, keys, deadbolts, spindles, and compact security hardware where fit, wear behavior, and stable assembly matter.

Typical concern: precise movement and repeatable lock function
SINTS reviews: material route, working surfaces, tolerance stack, finish, and assembly contact areas

Medical Assemblies

Medical Device Components

Stainless steel accessories, forceps parts, surgical-tool handles, syringe-related parts, and small medical components where consistency and surface quality are critical.

Typical concern: clean finish, repeatability, and controlled functional geometry
SINTS reviews: stainless grade, edge condition, polishing, inspection focus, and documentation needs

Power tool and industrial metal components

Tool Platforms

Power Tools and Industrial Hardware

Tool gears, pneumatic parts, guide-rod components, cylinders, forks, blades, and compact load-bearing parts for repeated-use mechanical products.

Typical concern: strength, wear life, and repeat-volume cost control
SINTS reviews: load area, tooth or bore control, heat treatment, surface finish, and production quantity

Appliances

Coffee, Appliance, and Household Equipment

Coffee burrs, cutters, portafilter parts, beverage-machine pieces, kitchenware fittings, sewing-machine parts, and household equipment components.

Typical concern: visible finish, food-contact or working surface needs, and stable replacement-part supply
SINTS reviews: material, hardness route, polishing or coating, edge condition, and packaging protection

Compact Devices

Consumer Electronics and Small Product Hardware

Hinges, buttons, phone parts, camera parts, watch components, headphone pieces, eyewear accessories, and compact structural parts for device programs.

Typical concern: miniature geometry, touch feel, cosmetic surface, and assembly fit
SINTS reviews: detail resolution, burr control, finish route, wear surfaces, and repeatable measurement points

Powder metallurgy gears and structural parts

Mechanical PM Parts

Gears, Bushings, and Structural PM Components

Sintered gears, bushings, bevel gears, helical gears, spider gears, stainless gears, agricultural parts, and compact structural components for mechanical assemblies.

Typical concern: tooth form, bore control, density, strength, and repeatable cost at volume
SINTS reviews: powder metallurgy fit, post-processing, tolerance targets, lubrication, and application load

View PM gears and structural parts

Drawing-Based Programs

Custom OEM Specialty Metal Components

Specialty alloy parts, personal-care hardware, pet hardware, security equipment parts, titanium or tungsten components, agricultural machinery pieces, and other OEM parts that begin with a drawing, sample, or application requirement.

Typical concern: matching the route to the function instead of forcing a preset process
SINTS reviews: material choice, functional surfaces, visible finish, edge safety, tooling logic, and annual demand
