The competition in the current home appliance market is becoming increasingly fierce, and the downward trend in terminal product prices and the improvement of standardization have put forward stricter requirements for cost control and product consistency in the supply chain.
In this trend, injection molding companies have become key to improving their risk resistance by optimizing every production process to be meticulous in their budgeting. As a high-end intelligent injection molding equipment manufacturer specializing in segmented fields, Donghua Machinery relies on JSeIII series two plate machines and D series
electric motorA mature model matrix such as the multi material P series deeply integrates the physical characteristics of equipment with the specific process requirements of household appliances, providing the market with solutions that are suitable for actual mass production and have a better input-output ratio.
01
Electrical structural components:
Balancing long-term stability and comprehensive cost reduction
Refrigerator multifunctional drawers, washing machine inner and outer buckets and other major electrical structural components usually have the characteristics of deep cavities and large weight, requiring a large mold opening stroke and matching
moldLarge volume. Heavy duty molds open and close day after day in long cycles of tens or even hundreds of seconds, which easily leads to equipment wear and tear, and is a direct and cruel test of the fatigue life of mold locking.
In response to such heavy load conditions, the Donghua JSeIII series large two plate machine has demonstrated extremely high long-term operational economy. The equipment not only adopts advanced two plate structure, which greatly saves factory space, but also in core execution,Adopting patented technology connecting rod type brake nut structure, strong synchronization, low impact, short action cycle, and low operating noise.This type of brake has precise and impact free characteristics, which can stably hold heavy molds and ensure that the outer bucket cycle is stably suppressed within 80 seconds during high load shaft operation, and the drawer is controlled between 55-76 seconds. Based on the stability of the underlying mechanical rigidity, the unplanned downtime rate has been significantly reduced, which is the fundamental cost reduction confidence for large-scale power production.
02
High demand appearance:
Ensure the consistency of molding for standardized products
External components such as air conditioning vents, centrifugal fan blades, and LCD display frames are directly aimed at end consumers. These types of components have extremely high requirements for surface defect free and dimensional stability - even small fluctuations in firing rate or holding pressure during the injection molding process can lead to high value
raw materialLoss and complete scrapping.
The core of producing parts with high appearance requirements lies in strictly eliminating molding variables. The Donghua D series electric motor adopts original imported internationally renowned brand ball screw, which has high rigidity, high precision, high durability, and ensures precision injection molding. At the same time, the control system integrates the AI process technology independently developed by Donghua, and through real-time collection and analysis of key process parameters during the molding process,Combining intelligent algorithms for dynamic optimization and adaptive adjustment, achieving intelligent compensation and flexible control of process parameters while improving equipment control accuracyTo ensure the stability and reliability of the molding process, the internal stress of large-area cover plates or fan blades is evenly released during molding, maintaining a high surface quality yield rate and fundamentally reducing the waste of expensive engineering plastics.

Intelligent small appliances and precision multi-color accessories:
Improve material adaptability and equipment universality
Small household appliances such as sweeping robot accessories, relay buckles, and electronic watch straps extensively use modified materials with poor fluidity and easy wear and tear. In order to improve texture, dual color encapsulation such as TPU and complex multi cavity molds are widely used. The frequent mold changes and idle equipment caused by fragmented orders are hidden costs that injection molding factories urgently need to address.
The Donghua Duo Material P series injection molding machine fits the rhythm of flexible manufacturing with extremely high equipment versatility. In response to the demand for multiple materials, the P series wide plate template is matched with a large pull rod inner distance,It can be installed with a single mold or flexibly hung with dual color molds; On the basis of the original mold, multi material injection molding can also be achieved.When dealing with special mixed color appearances, it is supported to melt and mix two colored adhesive materials through the same nozzle hole and inject them into the mold cavity, easily achieving a color mixing effect without clear boundaries. For high glass fiber materials, the equipment comes standard with high wear-resistant components to ensure long-term stable plasticization. The multifunctional feature of one machine allows injection molding factories to flexibly undertake various complex small household appliance orders, significantly reducing equipment idle rates.
Say goodbye to inefficient and single injection molding equipment
To stabilize production and optimize asset investment
The production difficulties of household appliance injection molded products vary from precision multi-color accessories for small appliances to large deep cavity structural components for large appliances. However, in the current industrial environment, stable equipment operation yield and reasonable asset investment are the cornerstones for the stable operation of enterprises. Donghua Machinery insists on deeply integrating objective equipment manufacturing technology with specific processes in segmented industries, providing more high-quality productivity solutions for the market with practical and precise mechanical bases.
