Precision Sheet Metal Fabrication and CNC Machining in Fremont with MASS Precision

A product that begins as a sketch usually needs several kinds of metalwork before it ships. There is a cut and bent enclosure, a machined bracket, some welds and a final assembly. MASS Precision is a Silicon Valley contract metal fabricator with a Fremont site, listed here for precision sheet metal fabrication, CNC machining, welding, assembly, prototyping and new product introduction support. This page explains how those steps connect and what to prepare for a quote.

Sheet metal and machining are different jobs

Sheet metal starts with flat sheet. A laser or punch cuts the shape, a press brake bends it, and the pieces are joined or fastened. It is a good process for enclosures, panels, chassis and brackets. Machining starts with a solid block or bar and cuts away material to reach a precise shape. It is better for thick parts, tight features and complex geometry. Many products use both, and a shop that offers both can reduce handoffs.

Welding and assembly

Welding joins metal pieces permanently. It adds heat, so a finished welded frame can move slightly, and critical surfaces are often machined after welding. The listing also names assembly, which can include fitting hardware, joining parts and building sub-assemblies. If assembly is part of your order, send an assembly drawing or bill of materials with the request.

Materials

The listing names stainless steel and aluminum. Stainless steel resists corrosion and is common in clean or wet environments. Aluminum is lighter and easier to cut and form. Tell the shop the exact grade you need, since two stainless alloys can behave very differently in bending and welding.

New product introduction

New product introduction, often shortened to NPI, is the stage between a working prototype and steady production. It covers things like designing for manufacturability, deciding on tooling and fixtures, setting inspection plans and working out costs. The listing mentions NPI support, so a team with a new design can ask about it during quoting.

Prototype to production

Prototype fabrication tends to use flexible methods, such as laser cutting and hand-fit welding. Production often adds fixtures that hold parts in the same position every time, which reduces variation. Say how many parts you expect over a year so the shop can plan the right setup.

Quality information

The listing shows ISO 9001:2015, ISO 13485:2016 and ITAR registration, as stated on the shop’s site. If your work needs special handling or documents, discuss them early.

What to send in your RFQ

• Drawings or 3D files for each part
• Assembly drawing or bill of materials
• Material and thickness
• Quantities now and expected later
• Finish, such as paint, plating or passivation
• Critical dimensions and tolerances
• Required delivery date

Local access

A Fremont site means shorter travel for design reviews and first article checks, which matters when an enclosure and its internal parts must fit together.

Design tips that lower cost

Sheet metal has simple rules that save money. Keep bend radii consistent, so one tool can form every bend. Keep holes a reasonable distance from bends, since forming can stretch a hole that sits too close. Avoid specifying tight tolerances on formed features unless function needs them, because bending is less exact than machining. If a part mixes sheet metal and machined features, note which surfaces must stay flat and which holes must line up. These small choices can shorten the quote and reduce rework.

Finishes

Common finishes for sheet metal parts include paint, powder coat, plating and passivation of stainless steel. The listing does not name finishes, so state yours and ask whether they can be arranged.
