ARLEX Application Guide

Injection Molding Machine Applications

Start With the Part, Mold and Production Target - Then Select the Machine

An injection molding machine should be selected around what it has to produce. Clamping force matters, but tonnage alone does not tell us whether a machine can run a particular mold efficiently.

The ARLEX Evaluation Principle

We review injection molding applications through the relationship between the part, plastic material, mold, and production target.

Quick Jump to 8 Industry Applications:

Explore Injection Molding Applications

1. Packaging Injection Molding Short Cycle & Filling

Covers thin-wall food containers, cups, lids, caps, closures, and buckets. High-speed injection configurations become relevant when cycle time and filling performance matter.

3. Household Products Injection Molding Machine Flexibility

Storage boxes, baskets, basins, kitchenware, and furniture parts. Designed for factories running multiple molds where tie-bar spacing, opening stroke, and mold size flexibility matter.

How ARLEX Evaluates an Injection Molding Project

A preliminary recommendation is built from 7 systematic steps rather than a simple tonnage table.

STEP 1
Understand the Molded Part: Overall dimensions, weight, wall thickness, projected area, and critical features.
STEP 2
Identify Resin & Conditions: Material viscosity, drying requirements, filler content, and screw configuration.
STEP 3
Check the Actual Mold: Mold dimensions, thickness, weight, cavity count, runner system, and opening stroke.
STEP 4
Determine Clamping Force: Calculated from projected area and cavity pressure with a safe safety allowance.
STEP 5
Match the Injection Unit: Shot volume, injection rate, pressure, and plasticizing capacity matching the resin.
STEP 6
Check the Production Target: Target cycle time, hourly output, shift duration, and future expansion goals.
STEP 7
Define Automation & Auxiliaries: Matching dryers, chillers, robots, mold temperature controllers, and conveyors.
