In injection molding, the gate and runner system determines how molten plastic flows into the mold cavity, directly affecting part quality, cycle time, scrap rate, and cost. Engineers and sourcing teams must balance functional performance, cosmetic requirements, and manufacturability when specifying gating strategies. For rapid prototyping and low-volume production, 6CProto provides injection molding services that

Demining equipment operates where failure is not an option. A probe head, a sensor housing, a handle, or a guard that cracks, softens, or absorbs moisture can turn a screening job into a dangerous one, so the plastics used in demining gear are selected and machined to standards the material's everyday cousins never face. High-performance

Mold flow analysis, also called injection molding simulation or plastic flow simulation, predicts how molten resin fills, cools, and solidifies inside a mold cavity before any steel is cut. Done well, it converts a plastic part design into a reliable mold and a repeatable process, flagging short shots, air traps, weld lines, and warpage risks

What Parting Line Precision Means Parting line precision is the geometric and dimensional control of the interface where mold halves, such as core and cavity, meet during plastic injection molding, overmolding, or liquid silicone rubber molding. It governs the visibility, height, width, and location of the parting line on the final part, and the consistency

EDM (Electrical Discharge Machining) processing is a non-traditional manufacturing method that uses controlled electrical sparks to shape hard metals and produce intricate geometries that are difficult or impossible to achieve with conventional cutting tools. For engineering teams developing prototypes, tooling, or low-volume production parts, EDM enables accurate creation of fine slots, deep cavities, sharp internal

In product development and B2B procurement, lead time is often the most critical factor influencing project success. A delayed prototype can stall design validation; an uncertain production schedule can break launch timelines. 6CProto, a rapid prototyping, precision CNC machining and on-demand custom manufacturing provider in China, builds its workflow around clear lead time estimation, production

A supplier's 1,000-hour salt spray claim tells you little unless you know what was tested and what counted as failure. An intact coated panel, a scribed panel and an assembled bracket with dissimilar fasteners can give different results. Salt spray resistance is a test-conditioned property, not a universal service-life rating. Updated October 3, 2026 For

A prototype bracket can fit perfectly and still give the wrong vibration result. A housing can survive a bench test yet behave differently after production molding. Automotive prototypes are useful when their geometry, material, manufacturing route and mounting conditions reproduce the variables the test is supposed to examine. Updated October 3, 2026 Start with the

bead blasting is the surface finishing process most often specified by two words and a smile, and most often rejected because the drawing never said what "matte" means. It is a controlled abrasion process that produces a uniform matte texture by blasting fine media at the part surface, and it is genuinely useful: it hides

Why Plastic CNC Earns Its Place Between Printing and Molding Plastic CNC machining sits in a useful gap in the manufacturing lineup. It is faster than injection molding because no steel tool exists, and it is stronger and more accurate than 3D printing because the part starts as solid, isotropic stock rather than fused layers.
