Product sticking refers to the failure to eject molded parts from molds.

Demoulding defects occur when demoulding resistance rises due to product dimensions, temperature and other conditions. Resin properties and molding parameters are contributing factors, yet product geometry and mold structure serve as primary causes. Special attention shall be paid to thin reinforcing ribs, hubs and tight pin core wrapping issues.

Excessive shrinkage around pin cores generates strong clamping force, leading to sticking. Low mold temperature and excessive holding pressure also trigger such defects.

Over-filling of upright elongated ribs and hubs makes ejection difficult. Contrary to pin core wrapping issues, this fault arises under low mold temperature and high holding pressure.

Insufficient draft angle increases demoulding resistance and causes sticking. Ejector pin layout exerts great impact; pins are preferably installed at high-resistance areas. Surface finish and damage of mold cavities also affect resistance and result in poor demoulding.

Sticking commonly occurs during injection molding. Excessively high injection or holding pressure leads to over-packed products. Molten plastic squeezes into gaps, locking parts inside cavities and causing sticking during ejection.

Excessive barrel temperature brings two problems. First, thermal degradation alters material properties, causing part fracture or tearing in demoulding process. Second, slow cooling extends molding cycle and reduces production efficiency. Temperature shall be adjusted properly according to material characteristics.

Unbalanced gate feeding also induces sticking, which requires targeted mold optimization.

Causes & Solutions for Product Sticking
Overfilling: Reduce injection volume, time and speed
Excessive injection pressure or barrel temperature: Lower relevant parameters
Long holding time: Shorten holding duration
Excessively fast injection speed: Slow down injection rate
Uneven feeding and partial overfilling: Adjust gate size and position
Insufficient cooling time: Extend cooling period
Abnormal mold temperature: Regulate overall and bilateral mold temperature
Mold undercut: Remove undercut via mold modification
Unbalanced multi-cavity or single-cavity gate feeding: Optimize flow path close to main runner
Poor venting design: Add sufficient exhaust channels
Long screw forward time: Cut down screw travel duration
Misaligned mold core: Align core and apply back draft locking
Rough mold surface: Polish cavity and apply release agent

Causes & Remedies for Sprue Sticking
Oversized sprue: Modify mold structure
Inadequate sprue cooling: Extend cooling time or lower barrel temperature
Insufficient sprue draft angle: Increase draft angle via mold revision
Misalignment between sprue arc and nozzle: Readjust fitting position
Rough inner sprue surface or undercut: Inspect and repair mold
Damaged sprue outlet: Conduct mold maintenance
Absent sprue lock mechanism: Install sprue lock

For sticking caused by pin core clamping, raising holding pressure and mold temperature effectively inhibits molding shrinkage.

In contrast, over-filled oversized parts embedded in cavities require reduced holding pressure and mold temperature to boost shrinkage.

Increase draft angles around cavities, hubs and reinforcing ribs. For tightly locked parts, add ejector pins to enhance ejection strength at critical positions.

Weld lines are common injection molding surface defects, which are formed when two or more molten plastic flows converge and fail to fuse completely. The root causes are insufficient melt temperature and injection pressure at the melt convergence position. The detailed professional analysis and improvement measures are summarized as follows:

1. Temperature Factor

Unreasonable temperature setting will lead to poor melt fusion. The main reasons include low barrel temperature, low nozzle temperature, insufficient overall mold temperature, low local temperature at the weld line area, and uneven molten plastic temperature. These conditions will cause the plastic melt to cool and solidify prematurely, resulting in obvious weld lines on the product surface.

2. Injection Molding Process Factor

Improper process parameters are the main controllable causes of weld lines. Low injection pressure cannot provide enough force for melt bonding; low injection speed will slow down the filling process, making the melt cool down before full fusion, thus forming visible weld marks.

3. Mold Factor

Mold structure and precision directly affect the filling and fusion effect of plastic melt:

• Poor venting: Insufficient venting at the weld line and mold components traps air during filling, which prevents tight fusion of melt flows.

• Unreasonable runner and gate design: Undersized runners, gates and nozzle holes limit melt flow rate and filling volume.

• Improper gate position: Excessive distance between the gate and weld line causes temperature and pressure loss during melt flow, which can be optimized by adding auxiliary gates.

• Unstable product wall thickness: Too thin overall or local wall thickness leads to rapid melt solidification. Offset core and mold will cause uneven wall thickness, resulting in inconsistent solidification speed.

• Unstable filling: Unbalanced filling speed and interrupted melt flow will cause discontinuous fusion of plastic flows.

4. Equipment Factor

Unqualified equipment operation status will affect molding quality. Insufficient plasticizing capacity leads to incomplete plastic melting; excessive pressure loss in the barrel of plunger injection machines will cause insufficient molding pressure, failing to meet melt fusion requirements.

5. Raw Material Factor

Raw material performance and purity affect molding effect. Contaminated materials will interfere with melt fusion; materials with poor fluidity have high filling resistance. The fluidity can be effectively improved by adding appropriate lubricants to eliminate weld line defects.

Injection molding accounts for approximately 60% of the total plant energy consumption. To achieve effective energy conservation, it is insufficient to merely rely on energy-saving technologies of production equipment. Comprehensive energy reduction can be realized through overall optimization from eight major dimensions: workshop supporting facilities, main equipment, molds, auxiliary machines, raw materials, processing technologies, new energy-saving technologies and production management.

1. Optimize Workshop Supporting Facilities
Rationally plan workshop layout to simplify process flow and material handling; reserve proper margin for power distribution to avoid idle energy waste; build high-efficiency insulated cooling water circulation systems; implement zoned independent control of workshop lighting and other facilities; conduct regular maintenance on public workshop equipment to eliminate extra energy consumption caused by malfunctions.

2. Optimize Main Injection Molding Equipment
Select properly sized machines to avoid energy waste from using large machines for small-sized products; prioritize all-electric and hybrid energy-saving injection molding machines equipped with innovative energy-saving heating systems, and conduct thermal insulation for heating and cooling systems; standardize equipment lubrication, adopt matched hydraulic oil and optimize hydraulic drive systems; adopt high-efficiency production modes such as multi-cavity injection molding and synchronous processing; regularly clean and maintain pipelines to ensure stable equipment operation, and use dedicated screws matching different raw materials to cut defective products and energy loss.

3. Optimize Injection Mold Design and Maintenance
Optimize the structure of runners, gates, cavities and temperature control water channels, and adopt hot runner molds and rapid heating & cooling forming molds; apply CAE mold flow analysis to streamline trial molding and mold modification procedures; balance material feeding of each cavity and adjust clamping force to the reasonable minimum value; carry out routine mold maintenance to keep temperature control water channels unobstructed and shorten molding cycles for energy saving.

4. Standardize Configuration of Auxiliary Equipment
Select auxiliary equipment with matched capacity to avoid excessive power output; arrange main machines and auxiliary machines in proper positions and rationalize their collaborative operation sequence; activate on-demand energy supply mode of equipment, equip with quick mold change devices to cut standby time, and perform regular maintenance to ensure stable operation.

5. Scientific Management of Production Raw Materials
Prioritize easily processable, low-energy-consumption and high-fluidity raw materials; strictly regulate raw material drying procedures with immediate use after drying to avoid repeated energy consumption caused by moisture regain; properly store raw materials and control the purity and cleanliness of recycled materials to prevent increased energy consumption resulting from defective products caused by impurities.

6. Streamline and Optimize Molding Processing Technologies
Set the shortest reasonable molding cycle on the premise of guaranteeing product quality; follow standard processing parameters provided by raw material suppliers and fix mature production parameters to reduce machine adjustment time; lower clamping force, cooling time and holding pressure duration within technical allowable range and eliminate invalid production procedures.

7. Apply New Energy-Saving Molding Technologies
Promote advanced molding processes including gas-assisted injection molding, micro-foaming injection molding and steam-assisted injection molding; implement integrated forming technologies such as in-mold assembly and in-mold spraying; adopt low-pressure and low-temperature molding processes when materials permit, and equip with energy regeneration systems to cut overall energy consumption via upgraded production modes.

8. Strengthen Factory Production Management
Strictly control product defect rate, as high-quality mass production is the core approach to energy saving; implement full-coverage maintenance for all production equipment to avoid energy waste from production shutdowns due to equipment failures; establish a workshop energy consumption monitoring system to accurately identify energy consumption loopholes; optimize production processes by learning from industry-leading operation modes, stabilize cooperation with upstream and downstream suppliers, and improve plant-wide energy-saving management regulations.
