Injection Molding Capabilities

The Haitian injection molding machine processes thermoplastic materials through a controlled molding cycle. Plastic pellets are fed into the barrel, heated and plasticized, injected into the closed mold cavity, held under pressure, cooled, and then released through the mold’s ejection system.

Operators can set and monitor key process conditions, including:

• Barrel temperature
• Injection speed and pressure
• Screw position and metering
• Holding pressure and time
• Back pressure
• Mold opening and closing
• Clamping force
• Cooling time
• Ejector movement
• Production cycle time

These parameters are adjusted according to the resin material, mold structure, wall thickness, component geometry, and appearance requirements.

Typical Applications

The equipment is used in our factory for:

• Precision plastic components
• Equipment housings and covers
• Electronic and connector parts
• Functional structural components
• Insert-molded parts
• Mold-trial samples
• Prototype plastic parts
• Low-volume production
• Repeat manufacturing batches

Commonly processed materials may include ABS, PC, PP, PA, POM, PMMA, TPE, and other thermoplastics selected according to project requirements.

Mold Trial and Process Verification

After a mold has completed machining, EDM, grinding, fitting, and assembly, it can be installed on the Haitian injection molding machine for practical testing.

During the trial process, technicians evaluate:

• Cavity filling behavior
• Flash and short-shot conditions
• Weld lines and flow marks
• Shrinkage and deformation
• Surface appearance
• Dimensional stability
• Cooling performance
• Ejection and demolding
• Cycle consistency

When an issue is identified, the molding parameters or mold details can be reviewed and adjusted based on the actual molded samples.

Role in Our Manufacturing Process

A typical workflow may include:

1. Mold assembly and fitting
2. Mold installation and setup
3. Resin drying and preparation
4. Initial molding-parameter setting
5. Sample production
6. Appearance and dimensional inspection
7. Mold or process adjustment
8. Repeat validation and batch production

Keeping injection molding within our factory allows the molding, mold-manufacturing, engineering, and quality teams to work within the same production system. This helps shorten the feedback path when adjustments are needed for filling, appearance, dimensions, cooling, or demolding.

The Haitian injection molding machines form part of our factory’s plastic molding capacity. Actual processing methods depend on the machine configuration, mold size, resin material, component geometry, tolerance requirements, and production quantity.
